People were ordered out of the water Friday morning in Solana Beach, Calif., after surfers pulled a man suffering from massive injures to his legs from the water.

KNSD-TV in San Diego said the victim was a 66-year-old man who was taking part in a group swim in Fletcher Cove. Witnesses said they saw the man flailing before he was pulled under water.

The U.S. Coast Guard and San Diego County Sheriff's Dept. dispatched helicopters to locate the shark, which is officials are speculating was probably a great white.

KGTV-TV in San Diego said people were being kept out of the water between the California cities of Del Mar and Carlsbad.
