A 35-year-old man died after being found unconscious near a creek in south Brooklyn Sunday.

Police officers found Christopher Wiltshire near Shell Bank Creek in Gerritsen Beach at about 5:30 p.m., cops said.

He was rushed to Coney Island Hospital, where he was declared dead.

Witnesses told police that Wiltshire had been riding a bicycle, although none was found at the scene.

Police are investigating, and the medical examiner will determine the cause of death.

Just last month, the body of a missing man, Brian Gewirtz, was found near the same creek after his family launched a citywide search to find him.

Gewirtz, who was 20 years old, had autism, his family said.
