Rioters "passed a police helmet round like a trophy" after PC Keith Blakelock was killed in Broadwater Farm disturbances in London in 1985, a jury has heard.
A witness known as Rhodes Levin, to protect his identity, told the Old Bailey he saw the defendant, Nicky Jacobs, kicking and punching the officer.
Levin, who himself admits kicking PC Blakelock "a few times", said he had seen Jacobs carrying a lock knife with a blade of around six inches.
He said that immediately afterwards Jacobs had told him he had "got a couple of dukes in" on the policeman, who was from Wearside.
Levin told the court that he saw a police helmet but could not remember who was holding it.
"They were passing it around, showing it," he said. "Like I say, it was like a trophy."
The witness said that days after the attack he had met Jacobs, who again boasted of getting "a couple of stabs" in on the officer.
Levin, who has convictions relating to Class A drugs, was sentenced for affray and handling stolen goods in relation to the riots, the court heard.
He was paid around £5,000 and given immunity from prosecution after providing information to a renewed investigation into PC Blakelock's killing in the 1990s.
Nicky Jacobs denies murder and the case continues.
