PATRICK AIR FORCE BASE, Fla. -- A day at the beach ended with a trip to the hospital. Friday morning, a shark attacked a 12-year-old boy in Brevard County. The boy was swimming in shallow water when the shark bit his leg. It's the second shark attack in Brevard County this week.

The boy was swimming near Patrick Air Force Base when he was attacked. He is in fair condition Friday afternoon. The shark left numerous marks on his left leg, including an 8-inch gash just below the knee.

"You could see on his leg, two or three good marks bleeding out," says Matt Adams.

It was the first thing Adams saw Friday morning as he walk across the beach with his surfboard. A 12-year-old boy had been bitten at least twice by a shark.

His parents told paramedics they saw the shark and it had to be at least six to eight feet long.

This is the second shark bite in central Brevard County this week. On Tuesday, a 20-year-old tourist from Venezuela was swimming in Cocoa Beach when he suffered a bite 6 inches to 8 inches in diameter just below his left knee. He was treated and released the same day from Cape Canaveral Hospital.

Most of the shark sightings are very close to shore. The predators are drawn to the shallow water to feast on baitfish. That appears to be the case here.

Lifeguards say it's really not uncommon to see sharks. It's just extremely rare to have two bites in one week.
