DARE COUNTY, N.C. — A teenager is in critical condition after another shark attack off the North Carolina coast, the sixth one in about two weeks.

The victim, said to be 17 or 18, was attacked at about 4 p.m. Saturday at a beach at the Cape Hatteras KOA campground in Rodanthe on Saturday, according to authorities. His name has not been released.

The victim was treated at the scene and airlifted to the hospital. He reportedly sustained injuries to his right calf, buttocks and both hands.

WTKR reported that the teen’s condition improved from critical to serious and he was out of the operating room as of about 11 p.m. Saturday.

He was swimming with several others when the incident occurred, but there were no other swimmers injured, according to officials.

The North Carolina coast has seen multiple shark-bite incidents in recent weeks.

This is the second incident in two days where a person was bitten by a shark in Dare County. On Friday, a 47-year-old man was bitten by a shark in Avon, N.C. His injuries were non-life threatening.

On Wednesday, an 8-year-old boy in Surf City suffered what appeared to be a shark bite. Police said the wounds were superficial and the injuries were minor.

On June 14, 12-year-old Kiersten Yow from Archdale and a 16-year-old boy from Colorado both lost their arms in shark attacks at Oak Island.

Yow lost her left arm below the elbow and suffered injuries to her left leg. Hunter Treschl lost an arm.

A 13-year-old girl was bitten while boogie boarding off Ocean Isle Beach on June 11. In that incident, the victim suffered non-life threatening injuries, but the shark took bites of her boogie board.
