Train rage killer’s gangland rap sheet revealed: Cannabis addict found guilty of stabbing passenger 18 times in front of his son, 14, is member of notorious gang and bragged of gun and knife convictions

  • EXCLUSIVE: Darren Pencille has links to London’s South Man Syndicate [SMS] 
  • Cannabis-addict was previously jailed for possession of a gun and a stabbing
  • The 36-year-old murdered Lee Pomeroy, 51, on Guildford to Waterloo train 
  • Knife-obsessed killer brushed past his victim and later stabbed him in the neck
  • Killer fled the train at the next stop where his girlfriend helped him escape police

  • Pencille was a paranoid schizophrenic – but refused to take medication and smoked super-strong cannabis instead

The ‘psycho’ train passenger who knifed to death a man on a commuter train in front of his teenage son was today found guilty of his murder.

Darren Pencille, 36, murdered 51-year-old Lee Pomeroy in a ‘savage and unrelenting’ onslaught on board the Guildford to London Waterloo train on January 4.

Pencille is a career criminal who bragged about his convictions for carrying guns and knives and fighting rivals ‘to the f***ing death’ for his South London gang, MailOnline can reveal today. 

One fellow gangmember who knew him well said: ‘He smoked weed constantly and was a complete psycho. I feel so sorry for the man he killed and his son’.  

The cannabis-addict was a lieutenant in the South Man Syndicate [SMS] crew in the capital whose members have terrorised the areas of Tooting, Streatham and Thornton Heath since the 1990s.

His extraordinary criminal past of more than dozen convictions – including slicing a man’s neck in a row over a Rizla cigarette paper – was revealed in a gang video posted on YouTube where he called on an enemy to meet and fight him.

It also emerged today that he was seen by a psychiatrist 24 hours before murdering Mr Pommeroy but was considered ‘no risk to himself or others’ – months after he told a hostel worker: ‘I’m going to kill you you c***’. 

Mr Pomeroy died on the eve of his 52nd birthday and was on his way to London for a day out with his 14-year-old son. A row broke out after Pencille jostled past the father and son in the aisle, sparking a war of words.

Knife-obsessed Pencille then pulled a blade from his pocket and knifed his victim 18 times including a fatal cut to his neck as the 14-year-old watched in horror.

Mr Pomeroy died a little over an hour later after suffering the fatal neck wound along with another eight to his torso and further cuts to his arm, hands and thigh in less than 30 seconds.    

Pencille refused to give evidence at his Old Bailey trial claiming he had acted in self defence. But jurors heard how 5ft 10in tall Pencille had a history of violence, having previously stabbed a flatmate in the neck over a minor disagreement in 2010 and had threatened to kill a staff member at a mental health hostel in June last year.

A jury deliberated for 19 and a half hours to find Pencille, of no fixed abode, guilty of murder.

His girlfriend Mitchell, 28, of Farnham, Surrey, was found guilty by a majority of 11-1 of helping him evade police after the attack.

‘He was our boy’s defender, guide and mentor – a guiding light forever extinguished’: Widow’s heartbreaking tribute to passenger killed in front of his teenage son

The grieving family of Lee Pomeroy said they had lost their ‘guide’ in life.

In a moving victim impact statement Mrs Pomeroy said her and her son’s lives ‘changed forever’ the day her husband’s life was ‘cut short in such an unnecessary and cruel way’.

‘Lee Pomeroy should have celebrated his 52nd birthday the day after he died,’ she added.

‘We had cards and presents for him which he never got to see.

‘Life has become empty.’

The court was told Mr Pomeroy, her husband of 18 years, ‘doted on’ their son and ‘supported all of his hobbies and interests’.

‘He was his defender, guide and mentor – a guiding light forever extinguished,’ Mrs Pomeroy wrote.

‘To compound the situation he was with his father when he died, and we have to eventually deal with that as well.

‘I am in tears as this statement is being written because my heart is broken.’

The court heard Pencille’s criminal record contains 14 convictions for 19 offences which also include burglary matters, witness intimidation and possessing a firearm.

Mitchell has seven convictions for 10 offences spanning 2011 through to last year and mostly comprising threatening words and behaviour and assault.

Mitchell is seen opening the door before Pencille is ordered to back towards the entrance with his hands on his head before he is handcuffed by officers and taken into a waiting police van.

Pencille can be heard saying ‘yes sir, yes sir’ and ‘please, I’m not going to do nothing, please’ before asking: ‘What’s this about sir?’

The killer, who faces life behind bars today, revealed his criminal past online after he was accused by another gang in south London of being a rapist and a police ‘snitch’.

In response Pencille revealed his extraordinary list of criminal convictions and handwritten police statements to deny the allegations by proving he was never guilty of any sex offences.

MailOnline can reveal today Pencille had been charged with rape in his home town of Loughborough, Leicestershire, but the charge was later discontinued.

In the YouTube video, Pencille says to his rival who calls him a ‘snitch’: ‘You’re not in my league bruv – you’re not on my radar. You ran, remember?’

When asked what he would say to anyone who believes he was a police informant he responds: ‘Suck your mum. Why don’t you come and confront me? I say that anyone’, adding: ‘SMS to the f***** death’.

As the train killer smokes cannabis in the background of the video, believed to be from ten years ago, a friend shows six pages of Crown Prosecution Service documents.

They reveal Pencille had been in prison and young offenders’ institutions on at least three occasions between 1999 and 2004. 

In 2004 he was convicted of possession of a gun and ammunition and jailed for just under three years.

Two years earlier he was twice caught carrying a knife on the streets of London, but was given a fine and community service.

Pencille also has one conviction for ABH, two for burglary, one of fraud, two thefts and driving without insurance.

The killer also was sent back to prison twice for failing to meet his bail conditions, MailOnline understands.

Pencille appears to have become an SMS member in his mid-teens and remained affiliated to the group, which had around 100 members at its peak, and known for attacking rivals Brixton, Peckham, Lambeth, and Streatham.

The train killer’s extraordinary rap sheet and his ‘fixation’ with knives

Pencille has a number of previous convictions and cautions for violence dating back to 1997.

Pencille had been charged with rape in his home town of Loughborough, Leicestershire, but the charge was later discontinued.

He was convicted of ABH following a fight in 1999 and twice convicted of having a blade, in 2002 and 2004.

In 2010 he pleaded guilty to GBH with intent after stabbing a fellow hostel resident in West Norwood, south London, twice in the side of his neck, cutting his artery, and once in the shoulder following a ‘minor disagreement’ over Rizla papers.

Pencille was jailed for four and a half years for that attack.

In 2018 he admitted common assault after growing agitated at another housing facility in Brixton, screaming at a staff member that they were a ‘c**t’, adding: ‘I’m going to kill you.’

Pencille hammered on the staff room door with a fire extinguisher before traipsing away clutching a ‘long metallic object’ towards his bedroom where a kitchen knife was later found.

Pencille was jailed for four and a half years for that attack.

Last year he admitted common assault after growing agitated at another housing facility in Brixton, screaming at a staff member that they were a ‘c**t’, adding: ‘I’m going to kill you.’

Pencille hammered on the staff room door with a fire extinguisher before traipsing away clutching a ‘long metallic object’ towards his bedroom where a kitchen knife was later found.

A consultant forensic psychiatrist who saw Pencille the day before the murder said he had been admitted to River House Medium Secure Unit in March 2015.

There he was observed to be ‘confrontational and agitated’ if he did not get his own way and ‘angry and threatening’ when his behaviour was challenged.

Pencille has been in contact with mental health services since 2003, has been diagnosed with paranoid schizophrenia and treated for psychotic symptoms.

But instead of taking his medication Pencille self-medicated with cannabis – which jurors heard would either calm him down or make him more argumentative.

Despite his violent tendancies and mental health problems he was deemed to have been ‘no concerns of risk to himself or others’ during his final appointment on January 3 – the day before the train murder.

Mr Pomeroy, who died on the eve of his 52nd birthday, was on his way to the capital for a day out with his 14-year-old son.

The Old Bailey has heard how the argument broke out after Pencille made a ‘rather snide’ remark as he jostled past the Pomeroys up the aisle moments after getting on.

As the father remonstrated with him and before any punches had been thrown, he whipped a knife out of his jacket pocket and stabbed Mr Pomeroy in the neck, jurors were told.

Pencille got off at Clandon, where he was picked up by girlfriend Chelsea Mitchell, 28, who was accused of ferrying him away from the scene, helping him change his appearance and carrying out internet searches into the killing.

Mr Pomeroy died a little over an hour later after suffering the fatal neck wound along with another eight to his torso and further cuts to his arm, hands and thigh in less than 30 seconds.

Jurors heard today how both Pencille and Mitchell used their phones later that to scour the internet for any mention of the murder.

They looked at articles in various websites about the stabbing, looked at tweets about it and researched hotels in the Aldershot, Portsmouth and Surrey.

Pencille, who was sporting a beard at the time, also did extensive research into where to buy hair clippers.

Mitchell picked up Pencille in her car and the two drove to her Surrey home and later went to Tesco in Chichester where she bought hair clippers.

The court was shown a video filmed by Mitchell, which showed Pencille with recently treated puncture wounds on his hand and elbow.

Mitchell, 27, who denied assisting an offender, lived with her violent boyfriend in Farnham, Surrey.

Neighbours told MailOnline how the couple made their lives a ‘living hell’ – and feared for their own safety.

One couple said: ‘They made ‘anonymous’ phone calls to my partners place of work claiming we are paedophiles.

Claiming we were making all kinds of noises day and night, which was simply all untrue.

‘Neither worked and moved in around Christmas 2017 and the first few months were fine.

‘Then around August 2018, their wild accusations about us, their loud music and repeated banging began.

‘I’ve been off work due to anxiety caused by the situation. My fiancée has now been signed off from her work.

‘We feel unable to move back to the flat because of what they put us through and now knowing what they have done, the thought of what could have happened to us is horrible’.  

‘What’s this about sir?’: Moment armed police arrested killer at his girlfriend’s flat after he went on the run for 18 hours following train rage murder 

Darren Pencille calmly asked ‘What’s this about sir?’ as armed police raided his girlfriend’s flat less than 24 hours after he knifed to death a train passenger.

The 36-year-old was described as ‘devious and dangerous’ by police as he was found guilty of murdering Lee Pomeroy the day before his 52nd birthday.

Pencille stabbed Mr Pomeroy 18 times in front of his 14-year-old son in a 27-second attack after a petty row aboard a London-bound train near Guildford in Surrey on January 4.

His girlfriend Chelsea Mitchell, 27, picked him up and bought hair clippers and razors for him to change his appearance as he sought to avoid capture. She was found guilty of assisting an offender.

Pencille can be heard saying ‘yes sir, yes sir’ and ‘please, I’m not going to do nothing, please’ before asking: ‘What’s this about sir?’

Detective Chief Inspector Sam Blackburn said he was ‘very calm in his nature and reaction’ and has never shown any remorse or taken any responsibility for what he has done.

‘I think it shows that he is both devious and dangerous and he set out to kill Lee Pomeroy and he succeeded, unfortunately, in doing that,’ he said.

‘It’s devastated not only Lee’s mother, wife, sisters and obviously… the son. But that has had a devastating effect on them, (and) I hope they can start to rebuild their lives following this verdict.’

Mr Blackburn said Pencille had a history of violence and a string of previous convictions, including one in 2010 for stabbing a man in the neck during another minor row.
