Police with tactical gear and officers on horses helped disperse crowds outside Target Center.

MINNEAPOLIS — The Minneapolis Police Department says one person was arrested and one person was issued a citation outside President Donald Trump's campaign rally in Minneapolis Thursday night.

The arrest was for damage to property and the citation was for disorderly conduct. Police used pepper spray to break up some of the fights outside the Target Center.

The skirmishes appear to have started after some of the demonstrators set Trump hats on fire.

Minneapolis police officers formed a line with horses and bicycles. Eventually the crowds thinned out.

Minneapolis Police Chief Medaria Arradondo released a statement from last night's event:

Earlier, opponents of the president chanted and carried signs in downtown Minneapolis Thursday evening as thousands of Trump supporters packed Target Center for his rally.

Several groups of demonstrators protested and attempted to block traffic near Target Center.
