CRESCENT BEACH, Fla. (AP) - Authorities are confirming that a boy bitten while boogie boarding off northeast Florida was bitten by a shark.

The St. Johns County Sheriff's Office says 10-year-old Seth Shorten of Gainesville was in waist-deep water off Crescent Beach on Wednesday morning when he was bitten on his right foot.

Sgt. Chuck Mulligan says the boy saw the 3-foot shark just before he was bitten.

Paramedics treated the boy for a superficial wound and his father drove him to a St. Augustine. Mulligan hospital.

Mulligan said Thursday that a shark tooth was found in the wound on Seth's heel. The boy needed stitches.

It's the fourth apparent shark bite along northeast Florida's beaches this summer.
