(AP) - Authorities in New Jersey say a man suspected of shooting and wounding an off-duty New York City police detective in Manalapan has surrendered.

Monmouth County Prosecutor Chris Gramiccioni tells the Asbury Park Press that after a 20-hour manhunt, Robert Dunbar of Staten Island turned himself in late Saturday night. He faces charges of attempted murder, aggravated assault and possession of a firearm for an unlawful purpose.

The prosecutor says Dunbar was taken to Monmouth County Correctional Institute in Freehold Township, with bail set at $500,000. There's no immediate word on whether he has an attorney.

The shooting happened Friday night at a Manalapan home. Authorities haven't released the NYPD officer's name or said why he was at the house.

An NYPD spokesman confirms the officer is assigned to the Brooklyn-based 63rd Precinct detective squad.
