A man has died after he "was bitten by what is believed to be a shark" in the waters of a Cape Cod beach Saturday, the Wellfleet Police Department said. The Cape Cod district attorney confirmed it was a shark attack.
The incident happened about noon when the man was swimming at Newcomb Hollow Beach in Wellfleet, Massachusetts, police said.
He was pulled from the water, given first aid and taken to Cape Cod Hospital, where he died, police said.
The man suffered "injuries to his lower extremities," an off-duty lifeguard told The Cape Cod Times.
The victim's was identified by the Cape and Islands district attorney's office as 26-year-old Arthur Medici of Revere, Massachusetts, on Boston's North Shore.
"I was in the water with him yesterday," friend Isaac Rocha told Boston ABC affiliate WCVB on Sunday. "We were surfing on boogie boards and I was about 5 to 10 yards from him. I saw him go down and then I saw him go back up and saw a lot of blood and he was screaming."
One beachgoer filmed lifeguards and emergency personnel taking the injured man off the beach on a stretcher.
"Witnesses at the scene told officers the victim and another male were about 30 yards off the beach boogie boarding when the attack occurred," the district attorney's office said.
The local police department is working with the National Park Service and the state police to investigate.
