A motorboat passenger was thrown overboard early Monday when the boat he was riding in hit a jetty off Long Island, police said.
The man remained missing hours later, and the pilot of the boat was arrested for boating while intoxicated, Suffolk County police said.
The boat hit a jetty in Sayville shortly before 1:30 a.m., police said. A 25-year-old man, who was not wearing a life jacket, was thrown overboard, they said.
The U.S. Coast Guard assisted officers from area police and fire departments in searching for the man, but he was still missing Monday afternoon, authorities said.
