Authorities have concluded a multi-agency marine search for a Brooklyn man who disappeared while swimming off the waters of an Amagansett resort Tuesday, East Hampton Town Police said Wednesday.

The missing swimmer was identified by police as 23-year-old Byron Dong Ha Kim in a statement.  Police said they have concluded their water search for Kim without finding him. 

Agencies that participated in the search included members with the East Hampton Town Police Department Dive Unit and Marine Patrol, aviation personnel with the U.S. Coast Guard and Suffolk County police, the Suffolk County Sheriff's Office and members with East Hampton Ocean Rescue. Employees with those agencies "conducted extensive searches of the area since Kim went missing on 8/18 at approximately 12:18 p.m. while swimming with friends," police said in the statement. 

However, East Hampton's Marine Patrol will continue searching the shoreline on four-wheel drive All-Terrain Vehicles, officials said.

Police had said Tuesday the missing man was with another man in the surf before both were pulled under the water in front of Windward Shores Ocean Resort.

One of the men was removed from the water, regained consciousness and was transported to Stony Brook University's Southampton hospital. 

Petty Officer Anthony Pappaly, a Coast Guard spokesman based in Manhattan, previously told Newsday the man who reportedly swept out into the water is described as tattooed and was wearing green fluorescent shorts.
