The U.S. Coast Guard is searching for a man who disappeared during a commercial shark diving venture in the Bahamas.

A Coast Guard news release said John E. Petty, 63, was with eight other divers in the water near West End, Bahamas, when he never resurfaced.

Coast Guard crews from Miami were searching for Petty by air and sea.

He was last seen 20 nautical miles northwest of West End by one of the divers in the group.
