As many as 500 protesters and 250 police were involved in a fourth night of violence Tuesday. Seven hours of confrontations ended around 2 a.m. Wednesday.

Sgt. Bob Dunn says an initially peaceful protest evolved into clusters of people who threw rocks at police, lit trash can fires, threw a Molotov cocktail at a police car and smashed windows in businesses.

Police used beanbag rounds and pepper balls.

Dunn says 20 adults and four minors were arrested.

He says a police officer, two members of the media and some protesters were injured, but nobody was hospitalized.
