Jurors have been shown a video of the moment an IT consultant was stabbed 18 times in 25 seconds while travelling on a London-bound train with his son.

The Old Bailey sat in silence during the graphic clip of the "quick and frenzied" attack on Lee Pomeroy, 51, who was stabbed by fellow passenger Darren Pencille on the 1.01pm service from Guildford to Waterloo on 4 January.

Pencille - who denies murder - looked straight ahead in the dock as the video was played out, avoiding screens set up in the court to display the footage.

It showed Mr Pomeroy board the train at London Road station with his son, with Pencille then seen walking in from another carriage and appear to say something as he walks past them.

The two men have an exchange - allegedly over the aisle being blocked - which leads Mr Pomeroy to follow Pencille into another carriage to continue the row.


In another video played in court, Mr Pomeroy's 14-year-old son said his dad got up "with a clenched fist".

He said: "My dad is very menacing because he is tall. The guy was taller than me, shorter than my dad. Normally when someone says something to my dad he won't let it go."

One witness told the court he heard Pencille shout "leave me alone" and "you're racist" to Mr Pomeroy after the pair arrived in the next carriage, and another, Megan Fieberg, said: "I saw them holding each other by the collars. They wanted a fight."

She said she then left the carriage because she "felt quite scared for my life".

In the CCTV from the train, both men repeatedly point in each other's faces before Mr Pomeroy begins to walk away, only to return so that he can again square up to Pencille and engage in more pushing and shoving.

The defendant then appeared to gesture with his hands and make a call, allegedly to his girlfriend, Chelsea Mitchell, to say: "I'm going to kill this man. He'll be dead."

Pencille, who has admitted possessing a knife, appeared to strike out at Mr Pomeroy's neck and then continue to stab him as his victim - who was a day away from his 52nd birthday - attempted to defend himself.

He is then seen to bend down and pick up his sunglasses and mobile phone before leaving the train.

Jurors have heard how he was picked up at Clandon station by 27-year-old Mitchell and taken to her home.

Pencille, of no fixed address, has denied murder, and Mitchell, of Farnham, Surrey, has pleaded not guilty to assisting an offender.
