A man jailed over the killing of a Somali youth is the son of former Ugandan military leader Idi Amin.
Wangita's parentage was not revealed until the end of the trial
Faisal Wangita, 25, was among a mob who beat Mahir Osman, 18, to death near Camden Tube station, London, in 2006.
He was jailed for five years at the Old Bailey in May for conspiracy to wound with intent and violent disorder.
He was one of 13 people convicted of offences including murder and assault. A court order banning reporting the case was lifted on Friday.
Mr Osman was stabbed 20 times, attacked with baseball bats, bottles and hammers, punched and kicked, the trial heard.
Ismail Mohamed, 20, of Haringey, Liban Elmi, 20, of Wood Green, and Hussein Ali Hussein, 17, Enfield, were found guilty of murder and jailed for 15, 14 and 10 years.

Wangita, who was charged with murder, was cleared of the offence.
The court heard Mr Osman's killing was the result of an escalating feud between rival Somali groups.
After the hearing, Det Ch Insp Michael Broster said the gang travelled to Camden "with the sole intention of attacking anyone belonging to the opposing group".
"It was a premeditated attack using a level of violence I have rarely seen," he said.
"This has been a complicated case to piece together due to various factors such as the time of night and the speed of the attack."
Wangita's papers said he was born in Uganda but he told police he was born in Saudi Arabia.

He stayed at a number of addresses in London. He arrived in England some time ago and was living here legally with his mother.
He had previous criminal convictions for possessing an offensive weapon, theft, fraud and threatening behaviour.
President Amin had 40 officially-recorded children from seven wives.
Up to 400,000 people are believed to have been killed under Mr Amin's rule in the east African state between 1971 and 1979.
He fled to Libya, then Iraq, before finally settling in Saudi Arabia, where he died of multiple organ failure in 2003.
