KANEOHE (KHNL) - A labor day outing at a popular site on Windward Oahu ends in violence.
Paramedics took three people to the hospital after a fight erupted at the Kaneohe sandbar.
Witnesses say dozens of people were involved in the brawl.
The sandbar is located off Heeia Kea Pier.
Witnesses say a group of people out on the water were starting fights - boat by boat.
Police say, the victims were injured by beer bottles.
"We had perfectly good clean fun all the way up till now," said witness Gregory Marshall. "I don't know about the stabbing, I don't know if there was a bottle broken or somebody had a knife. I wouldn't doubt it because it was a mob scene coming at us. And when you're in the water, it's kind of confusing and none of us wanted to fight. It seemed like forty, fifty guys wanted to fight."
It was the fear of such uprisings that led to a bill last year in the legislature that would have made the sandbar a state monument.
If passed, the bill would have allowed the state to impose regulations, that included banning alcohol and commercial activities.
But Governor Linda Lingle vetoed the bill, saying the Department of Land and Natural Resources already enforces rules to keep it safe, clean, and secure.
No arrests were made following Monday's incident.
The Department of Land and Natural Resources is investigating.
