An 11-year-old boy was in guarded condition Sunday night at a Houston hospital after firefighters say he was bitten on the arm and leg by a shark at Bryan Beach (search) on the Gulf of Mexico.

The boy, whose name was not released, was flown by helicopter to Memorial Hermann Children's Hospital (search). Amy Berryman, operations administrator, said his condition was being evaluated in the emergency room.

The attack occurred about 8 p.m. as the boy was fishing for trout with his family, Fire Marshal Chris Motley told The Facts newspaper for a story in its Monday editions.

Motley said the boy was carrying a bag of fish when he was bitten three times once on the right arm, and above and below his right knee.
