Three pro-Palestinian protesters were arrested on the University of Michigan campus Wednesday, MLive Media Group, a local news organization, reported.

The TAHRIR Coalition, a campus student group, led the protest in response to an event held by the university’s Students Supporting Israel chapter, which featured several Israel Defense Forces soldiers.

Melissa Overton, the university’s deputy chief of public safety and security, told MLive that the individuals arrested were not affiliated with the university. She said the protesters blocked the exit to an underground parking garage and refused to move when ordered to. 

They were charged with resisting and obstructing police, attempting to disarm an officer, disorderly conduct, and outstanding warrants, Overton said. The case has been forwarded to a prosecutor, she noted.

Erek Mirque, a member of TAHRIR, told MLive that the arrests came as a surprise and that he was unaware of any confrontation with officers before the arrests.

“We did not expect the situation to escalate the way that it did,” he said.
