One of the men on trial for the murder of lawyer Tom ap Rhys Pryce has accused his friend of killing him.
Mr ap Rhys Pryce was stabbed in the chest
Delano Brown, 18, told a jury Donnel Carty, 19, stabbed the 31-year-old after they chased him from Kensal Green Tube station in north-west London.
Mr ap Rhys Pryce was stabbed twice in the chest and died on the pavement near his home on 12 January.
Carty, of Kensal Green, and Brown, of Sudbury Hill, both north-west London, deny murder.
The defendants have both pleaded guilty to robbing a middle-aged man in Kensal Green station earlier that evening.
'Kicked in face'
Brown told an Old Bailey court they had targeted him as he made his way home at 2330 GMT.
His counsel Courtenay Griffiths QC asked: "Who stabbed Tom ap Rhys Pryce?"
Brown replied: "Donnel Carty."
Brown said Carty "fly-kicked" Mr ap Rhys Pryce in the back.
"He just dropped to the floor," he said. "He tried to get back up and Carty kicked him to the face."
Brown said he picked up Mr ap Rhys Pryce's belongings from the ground as the lawyer struggled with Carty.
They were fighting," he said. "He was trying to get away and Donnel tried to stop him. He was trying to fight with Donnel."
After picking up a mobile phone, Brown noticed Mr ap Rhys Pryce was bleeding and "holding his chest".
"I was trying to pull back Donnel. I said: 'Come on, let's go now'.
"He shouted at the man: 'What else have you got?' The man said: 'Nothing. You have got everything'."
Brown said they ran off to Carty's home.
He said he did not see or know Carty had a knife.
The trial continues.
