Protesters faced off against law enforcement at the Republican National Convention Wednesday with several arrests, two injured officers and one person setting himself on fire.

Cleveland police said 22 protesters have been arrested so far. Law enforcement said no media, only protesters, were apprehended.

Authorities closed the exit on 4th and Prospect in Cleveland temporarily Wednesday evening, directing convention attendees to leave through a different exit. Things really got out of hand when activists from the KKK, Black Lives Matter and the Westboro Baptist Church reportedly began throwing urine, KPLCTV reports.

A little after the arrests, a group of about 20 protesters began running in the streets dancing, chanting and singing.

“Right now, I think so far, so good,” said Police Chief Calvin Williams Wednesday. “We’re still out there, we’re still vigilant, to make sure we finish this day and the last day tomorrow on a positive note.”
