An investigation was underway Sunday in New York after two people were stabbed and one was bashed with a bottle in a melee at a party yacht docked at a Brooklyn pier, authorities said.

Officers responding to a 911 call Saturday evening found a 32-year-old man who had been stabbed in the torso, a 40-year-old man with multiple stab wounds and a 28-year-old man who had been hit in the head with a bottle

Social media video from the scene showed chaos as at least eight people, including at least two women, wrestled and punched each other on the pier. One man appeared to stomp on the leg of a woman on the ground. A security guard helps break up the fight, and people are shown carrying a wounded person to an ambulance.
