A Royal Caribbean cruise ship was forced to return to shore after a brawl onboard left two passengers hospitalized.

Wonder of the Seas went back to Port Miami on Monday night following reports of an altercation.

A witness told local10 that passengers were seen running to the pool area before the captain announced the return to port.

Wonder of the Seas, the fourth largest cruise ship in the world, was set to be on a four-day round trip throughout the Bahamas, stopping at Coco Cay, and Nassau before returning to Miami.

Images on social media showed a large police presence at the port - alongside several ambulances.
