A man was arrested Wednesday evening on suspicion of aggravated assault for chasing people around with a long pole on the 16th Street Mall.

Denver police received a call at 6:07 p.m. of a shirtless man chasing people and hitting them with a plastic pole, said Doug Schepman, a Denver Police spokesperson. Police arrived on scene three minutes later.

“We believe having more officers down there did help with having a very quick response,” Schepman said. He referenced the Denver Police Department’s plan to ramp up security on the mall.

A Facebook video of the attack posted by Caleb Bonham received more than 606,000 views and nearly 3,000 comments by 11:30 p.m. Wednesday. It shows the shirtless man, whose name has not been released, chasing and hitting people on the mall near the McDonald’s on the corner of 16th Street and Cleveland Place.
