(AP) — A 19-year-old is in critical condition after suffering alcohol-related injuries at the Fourth of July celebration called “floatilla,” while hundreds of other people had to be rescued during the float party off the coast of Waikiki, authorities said.

Lifeguards estimated 8,000 to 10,000 people came to Tuesday’s celebration. Honolulu Emergency Services Department spokeswoman Shayne Enright said the 19-year-old woman was in critical condition due to intoxication.

At least 10 other people were hospitalized in serious condition due to alcohol-related injuries, Enright said. Those taken to hospitals ranged from age 17-26, she said.
