Urine-filled balloons flung amid anti-police protest

(CBS) DENVER - Denver police arrested four protesters at a downtown mall Saturday night, who they said spray-painted a bus, a police car and several cars sitting in traffic. They also spray-painted anarchist symbols onto vehicles and reportedly tossed urine-filled balloons, according to CBS Denver.

Authorities said those arrested were anti-police protesters.

One juvenile was cited.

Most of the group scattered, but police will continue to patrol downtown streets of the Mile-High City.
