A Chicago police officer was wounded during Donald Trump protests at UIC downtown.

A video on social media shows an officer bleeding from an apparent wound to the head at Van Buren and Racine.



Rogers Park resident Jeff Orr, who took the video, said the crowd gathered because there was a police line.

"There was a mix of Trump supporters and protesters so don't know what happened," Orr said. "It was a very tense situation that indicative of the tension in America right now."

Meanwhile, Chicago Police said five people were arrested amid the chaos that erupted following the announcement.

Additionally, two CPD officers were wounded – both with non life-threatening injuries – though one officer was struck on the head by a bottle. Police did not confirm that the video above shows that officer.

"It is unfortunate that parties on both sides allowed their political views to become confrontational, and that's unfortunately resulted in that scuffling and the arrests that were made," Interim Chicago Police Superintendent John Escalante said at a Friday evening press conference. "We were confident that we had the right security for the event and the protesters as well."

The department previously said it had not advised Trump’s campaign to cancel the rally, and did not issue any public safety threats or safety risks.
