A parolee at a facility for sex offenders in Melbourne's north escaped during a supervised community outing on Thursday.
The 37-year-old walked away from a car park about 11am on Thursday while on a supervised trip to help his reintegration in to society.
He handed himself in to Collingwood police station shortly after 8pm.
He is housed at the Disability Forensic Assessment and Treatment Service for sex offenders with an intellectual disability.
His escape was a breach of parole to undergo compulsory treatment for serious indictable offences.
The secure facility in Yarra Bend houses some of the state's worst sex offenders, who are allowed into the community, mostly in the Fairfield, Heidelberg and Northcote areas. He was returning from an escorted trip when he disappeared.
Police searched the immediate area but were unable to find him.
Members of the public had been warned not to approach the man.
Police released an old image of the parolee, who had since grown a moustache.
