Police said a man died after a shark attack off Cape Cod.

WELLFLEET, Mass. —Aman boogie-boarding off a Cape Cod beach was attacked by a shark on Saturday and died later at a hospital, becoming the state’s first shark attack fatality in more than 80 years.

The 26-year-old man from Revere succumbed to his injuries following the attack in the waters off Newcomb Hollow Beach in Wellfleet at around noon, Wellfleet Police Lt. Michael Hurley said.

Life-saving measures were attempted on the beach before the man was taken to Cape Cod Hospital in Hyannis, where he was pronounced dead, State Police spokesman David Procopio said. The beach has been closed to swimming.

The attack is the first fatal shark attack in Massachusetts since 1936, and the second shark attack this season.

A 61-year-old New York man was severely injured Aug. 15 after fighting off a shark off Truro, about 4 miles north of Saturday’s attack. He’s currently recovering in a Boston hospital.

“Today is just keeping everyone out of water,” Hurley said. “There’ll be a determination later about what the town wants to do with the beaches going forward.”

Beachgoers said the Wellfleet beach is popular with surfers, and with sunny skies and warm temperatures Saturday it was busy, even though the summer season was over and lifeguards were no longer on watch.

Joe Booth, a local fisherman and surfer, said he was on shore when he saw the man and his friend boogie-boarding when the attack happened.

He said he saw the man aggressively kick something behind him and a flicker of a tail from the water. He realized what was happening when the friend came ashore dragging his injured friend.

“I was that guy on the beach screaming, ‘Shark, shark!’ ” Booth said. “It was like right out of that movie ‘Jaws.’ This has turned into Amity Island real quick out here.”
