June 11 (UPI) -- Police in the Bahamas arrested five U.S. nationals at a port after an altercation with cruise passengers and law enforcement earlier this week.

The five people were involved in a physical altercation on Monday with passengers on a cruise ship in the Nassau Cruise Port area and, after they were arrested, started a second altercation with police officers, the Royal Bahamas Police Force said in a news release.

Four police officers were injured in the second melee, with one hospitalized with a "serious injury" to his left shoulder.

One person who informed police about the initial altercation with the ship's passengers was asked to come to the police station to give a statement but declined the interview, police said.
