WAIANAE, Hawaii — Lifeguards say they have a rescued a woman after what appeared to be a shark bit her arm and shoulder at a popular Hawaii surfing beach.

An expert will examine the woman’s wounds to confirm that it’s a shark bite.

The Honolulu Emergency Services Department says lifeguards on Wednesday paddled out on rescue boards and brought the woman to shore. Surfers in the water helped. The woman was about 300 yards from shore at Makaha Beach.

The woman was taken in serious condition to a trauma center.

Officials say she frequents the Oahu beach regularly.

No information was available on the type of shark.

Lifeguards have posted shark warning signs and cleared the water. Officials will reassess Thursday morning whether to reopen the beach.
