Watch: Huge brawl erupts on Carnival cruise ship, Coast Guard involved with 60-person brouhaha sparked by alleged threesome

A massive brawl erupted on a Carnival cruise ship this week. The huge brouhaha was so intense that it continued on several different floors of the Carnival Magic cruise ship.

Video shows dozens of cruise passengers engaging in a brawl during the last hours of a Caribbean cruise. Around 2 a.m. on Tuesday, an argument exploded on the dance floor.

Citing travel agent Theresa James, who was aboard the cruise, Fox News reported, "An alleged threesome between passengers had upset their significant others when they learned of the rendezvous."

Authorities estimated that as many as 60 people were involved in the all-out brawl. The ship's security attempted to stop the fighting, but the guards were overwhelmed by the hostile crowd. The fight started on the dance floor on the fifth floor, spread to the casino on the same floor, and eventually fizzled out on the first floor of the vessel. The melee lasted for about an hour.

An onlooker said some passengers were injured by being cut by glass.

The fisticuffs broke out in international waters.

The Carnival cruise ship called the U.S. Coast Guard for assistance. The Coast Guard escorted the cruise liner back to New York City, according to the New York Post. New York police were waiting at the dock when the Carnival Magic arrived in port.

WNBC reported, "No injuries were reported and no weapons were involved, according to the U.S. Coast Guard. Neither the Coast Guard nor the NYPD boarded the vessel, officials said. Passengers disembarked without further incident upon their NYC arrival Tuesday."

Cruise Law News reported, "The Coast Guard notified the New York Police Department which also clearly does not have jurisdiction to investigate crimes on Panamanian-flagged ships which are outside of New York waters."

"Last night while Carnival Magic was returning to New York, a number of guests were involved in an altercation in a nightclub," Carnival said in a statement. "Thankfully no serious injuries were reported and our onboard security team intervened. The ship arrived as scheduled this morning and shoreside law enforcement authorities were notified and met the ship to interview suspects and witnesses and conduct an investigation."

The eight-day cruise left New York City on June 20 and stopped at ports in the Dominican Republic, Turks and Caicos, and a private island in the Bahamas before returning to the Big Apple.
