Police are asking for the public's help in identifying suspects in the assault and robbery of a man confined to a wheelchair as he was leaving church in Riverhead earlier this month.

Cash and prescription medications were stolen from the man in the June 1 attack -- and police are offering a cash reward of up to $5,000 for information leading to an arrest.

Suffolk County and Riverhead Town police said the robbery occurred on Maple Avenue near the train tracks, north of Second Street, at about 10:30 p.m., not long after the victim had left the nearby United Methodist Church.

Police said the victim, who is in a wheelchair because of a prior car crash, was approached by the suspects near the Long Island Rail Road tracks and knocked out of his chair after being attacked with weapons, possibly sticks or pipes. It was not clear how much money was taken.

Police ask anyone with information to call Crime Stoppers at 800-220-TIPS or the Riverhead Town police Detective Division at 631-727-4500, ext. 327. All calls will remain confidential, police said.
