A section of shoreline was closed after a shark attack Saturday in waters off central Maui, and an aggressive shark was spotted off of Maili Beach Park in Waianae.

On Maui, high surf from Hurricane Ana brought a 12- to 14-foot tiger shark to the surfing site called "Freight Trains," about 100 yards from the condominiums at Maalaea.

Professional surfer Kaleo Roberson said at about 11:15 a.m., he was sitting on his surfboard near his three sons, a 6-year-old and 8-year-old twins, when he saw the shark coming straight at him from 10 to 15 feet away.

Roberson said he moved a leg and stuffed his surfboard into the shark’s mouth.

"The thing was so close  to me I looked right down the throat," he said.

Roberson said the then used his board to hit the shark twice before it spun around and swam away.

Officials shut down a two-mile stretch of shoreline, and said they would continue to search for the shark.

On Oahu, a 12-foot shark prompted lifeguards to post signs warning beachgoers. 

The shark was spotted at about 2 p.m. Saturday. 

Shayne Enright, spokeswoman of the Ocean Safety and Lifeguard Services said, "We cleared the water which thankfully wasn’t too crowded."

Warning signs will likely remain posted at the beach park for the rest of the day.
