Students clashed against Tucson Police officers on University Avenue Saturday, March 29, 2014, in Tucson, Ariz. after Arizona's loss to Wisconsin 64-63 in the West Region NCAA final.

TUCSON, Ariz. - Repeating a scene from 13 years ago, several hundred Arizona fans and Tucson police clashed in the streets following the University of Arizona basketball team's loss to Wisconsin in the NCAA tournament.

Authorities say 15 people were arrested Saturday after fans hurled beer bottles and firecrackers at officers. Officials at the University of Arizona vowed to punish any students who participated in the fracas.

Tucson police Sgt. Pete Dugan says the clash began after crowds leaving bars and restaurants near campus filled University Boulevard after the game. He says officers fired pepper spray, pepper canisters and pepper balls to try to disperse the crowd.

No officers or fans were injured in the unrest that lasted more than an hour.

In 2001, police arrested 17 people after Arizona lost to Duke in the national championship.
