Waters off Ho'okipa Beach Park were closed for two hours yesterday after a shark sighting on the north shore of Maui, county Chief of Aquatics Mary Kielty said.

The shark was estimated to be a 12-foot tiger shark, and it was spotted at 11:15 a.m. about 150 yards from the surf break.

Ho'okipa, a popular surfing spot, was closed from 11:30 a.m. to 1:30 p.m. for one mile both north and south of the surfing reef.

The beach park remained open.

Warning signs were posted in the area, and no injuries were reported.
