Sandberg reported police clashed with some protesters, wielding their night sticks and batons.

First Precinct Commander Ed Winski checked a protester who refused to stay on the sidewalk. When the protester came back into the street, Winski hurled his megaphone down and wound up rolling around in the street with the protester, throwing punches. Other officers surrounded the two, throwing punches. The protester was arrested.

“It wouldn’t surprise me if he threw down his megaphone in order to help make an arrest,” Browne said.

Police say the protesters were throwing bottles and bags of garbage at officers, triggering the police response, Sandberg reported. Police say they were trying to control the situation when it got out of hand.
