A shark attacked a 34-year-old Kailua-Kona woman Friday while she was surfing at Halaula Lighthouse in North Kohala, Hawaii County police said. 

The woman suffered injuries to two fingers, and was taken at 11:12 a.m. to the North Kohala Community Hospital.

A friend saw what he described as a 12- to 15-foot tiger shark with her board in its mouth, police said.

The friend said he "saw her board lift out of the water with her on it," police said in a news release.

"The shark then began to tow the board out to sea, dragging the woman, who was attached to it with a surfing leash," the press release said. "As the male friend paddles toward her, the shark let go of the surfboard. After the friend hit the shark, it swam away."
