EDGARTOWN, Mass. (AP) — A 60-year-old man was charged Friday with disorderly conduct for allegedly lying about seeing two great white sharks off a Martha Vineyard's beach, authorities said.

Edgartown police Chief Paul Condlin said Michael Lopenzo warned people to get out of the water at the Joseph Silva State Beach on Thursday. Lopenzo claimed he had seen two sharks about 22 feet long and 3,000 pounds each while he was working on a fishing boat.

Officials closed the beach, but Condlin said investigators later determined Lopenzo was lying.
