AVALON, Calif. (AP) — Authorities say a 15-year-old boy has been bitten on the hand by a shark while kayaking off Santa Catalina Island.

Los Angeles County lifeguards say the boy, who was taking part in a Boy Scouts camp, was with his father Wednesday morning when their kayak was bumped by what was believed to be a shark of unknown type or size.

Authorities say the boy put his hand in the water and was bitten. He was airlifted in stable condition to a hospital for surgery.

His wound isn't believed to be life-threatening.
