Chindamo was released from prison in July
The killer of headmaster Philip Lawrence has been bailed by detectives investigating a street mugging.
Learco Chindamo, 30, was arrested on Wednesday on suspicion of mugging a young man after he used a cash machine in Camden, north London.
The attack took place on 13 November in Belmont Street at the junction with Chalk Farm Road.
Police said they suspected a gang of people may have been threatening people who used the machine.
A Metropolitan Police spokesman said three men and a woman were suspected of mugging the victim, aged in his 20s, near a Sainsbury's supermarket.
Detectives want to speak to anyone who saw the group acting suspiciously or others who may have been approached or threatened near the cash machine.
Headmaster's murder
Learco Chindamo was freed in July, 15 years after the killing in Maida Vale, in north London, and allowed to remain in Britain.
Father-of-four Mr Lawrence, 48, was fatally wounded after going to help a pupil who was being attacked by a gang, which included Chindamo, then aged 15.
Chindamo was jailed indefinitely for the murder of Mr Lawrence outside St George's Roman Catholic School in 1995.
He was convicted of the murder in October 1996 and ordered to serve a minimum of 12 years.
A judge ruled that he could not be deported to Italy, where he was born, because it would breach his human rights as he has spent most of his life in Britain.
Philip Lawrence's widow Frances Lawrence has complained that the authorities did not tell her where Chindamo was living and that his rights seemed to be put above hers.
The prime minister's spokesman said David Cameron was "very concerned" about Mrs Lawrence's distress over his recall to prison.
But he said the law meant there was no choice but to withhold details of Chindamo's address.
"It is not a question of giving more rights to criminals than to victims. It is an issue about compliance with the law," he said.
