ST. PAUL - St. Paul police made one arrest after bottles and rocks were thrown by a rogue group of protesters who broke away from a peaceful demonstration outside the governor's residence in the aftermath of a fatal police shooting.

Police say the group made their way to a nearby commercial street where they broke the storefront window of one business as well as windows of an unattended police squad car.

Sgt. Mike Ernster says officers used a chemical irritant to stop the perpetrators. He says the individual arrested could face a charge of felony riot. No serious injuries were reported.

Police say demonstrators continued to gather peacefully outside the governor's mansion.
