A 58-year-old woman was taken to a hospital after being bitten by a shark as she was swimming off South Maui this morning, state officials said.

The attack, by what’s believed to be a tiger shark, occurred at about 10:30 a.m., roughly 40 yards off of Kamaole Beach Park No. 1 near Kihei, according to the Department of Land and Natural Resources.

Officials said it occurred in waters fronting the lifeguard tower. Lifeguards treated the woman before she was taken to the hospital, where her condition is unknown at this time.

Shark warning signs have been posted on the shoreline from Cove Park to Kamaole Beach Park No. 3.

Kihei resident Jordan Snow said the swimmer, named Barbara, was by herself near the buoy when the attack occurred. “Suddenly, I heard Barbara was saying, ‘everybody, out of the water. There’s a shark.’”

The victim was able to swim on her own to shore, where lifeguards used a tourniquet to control the bleeding from injuries to her upper right leg. “She was bleeding really badly when she got out of the water,” said Snow.

Snow volunteers for a group of women called “Maui Mermaids,” who regularly swim near the shoreline.

Jordan said the victim swims at Kamaole Beach every morning.
