(CNN) Violent brawls and disruptive behavior on a 10-day Carnival Line cruise in the South Pacific led the ship to dock early so Australian police could remove a large family of 23 people.

Cellphone video from the ship shows passengers on the Carnival Legend tussling with each other and security officers amid shouting and screams from alarmed onlookers.

The video also shows security officers kicking passengers after they were down on the floor.

"We have a zero tolerance approach to excessive behavior that affects other guests," Carnival Cruise Line said in a statement. "In line with this policy, we cooperated fully with local authorities in Australia to remove a large family group who had been involved in disruptive acts aboard Carnival Legend.

"Our security team responded in several instances to extremely unruly behavior by these guests. One particular altercation in the nightclub began when the group physically attacked other guests."
