Police are no longer looking for Melvin Coy, who was jailed for helping the killer of Liverpool schoolboy Rhys Jones.
Merseyside Police made an appeal for his whereabouts after he allegedly breached the conditions of his licence for release from prison.
Coy, 31, was jailed for seven years after being convicted of assisting an offender in the aftermath of Rhys's murder.
Merseyside Police said he handed himself in at a police station earlier today.
Soldiers from the 36 Engineer Regiment are in Liverpool are helping to build a new fence around the Rhys Jones Centre today.
Fencing going all around the building was on the original plans for the centre, but a lack of funding means it was never completed.
The centre was opened last September in memory of Rhys Jones, who was killed by a stray bullet, aged 11, in a shooting in 2007.
His death became symbolic of north Liverpool's gang warfare problem. The community centre named after him helps local youngsters escape poverty and crime.
A new community centre named in memory of Liverpool school boy Rhys Jones will be officially opened today.
