BEND, OR -- Saturday afternoon a fight broke at Pilot Butte Park involving Trump supporters and Black Lives Matter demonstrators. Most of the day was generally peaceful, however, towards the end of the event, a 23-year-old Bend man stole a Trump flag leading to punches being thrown and people being sprayed with bear spray and a report of one person pointing a firearm at another.  Approximately 100-150 people in total were present at the park.  According to Bend Police Chief Mike Krantz, as officers were leaving the park some demonstrators blocked their exit and had to be removed. During this, several of the people punched, hit and assaulted officers. Police are asking if any person was a victim of a crime at Saturday's event, to contact them so they can conduct an investigation.
