WAVES, N.C. — The National Park Service says a 17-year-old boy was attacked by a shark on North Carolina’s Outer Banks, the second such attack in as many days and the sixth attack in the past two weeks.

According to a post on its Facebook page, rescue personnel and park rangers responded to the boy, who received what they described as injuries to his right calf, buttocks and both hands on Saturday. Officials said the boy was swimming with others when he was bitten, but no one else was hurt.

The park service said the unidentified teen was airlifted to a Norfolk, Virginia, hospital.

On Friday, a man was bitten on his back and leg in Avon.
