The 911 calls from Elks Lodge 106 in north Minneapolis came after a man overturned tables, threw punches and pulled out a knife.
Minneapolis cops also heard that someone had fired shots.
So they stormed the Plymouth Avenue club near midnight on April 21 with guns drawn, ordering dozens of people out and others to get down on the floor. But in the process of finding the perpetrator and checking for weapons, some say that white officers acted improperly in a crowd of middle-age, black attendees.
Seven witnesses shared their concern with the Star Tribune in separate interviews. Four of them said they heard officers use racist epithets, and six said they experienced or saw officers use excessive force.
Witness and civil rights activist Ron Edwards said he mailed a complaint Thursday to the internal affairs unit of the police department.
Sgt. Steve McCarty, a police spokesman, neither confirmed nor denied the allegations and said police would investigate any complaints filed about the incident.
"If there are [reports of] shots fired inside of a crowded Elks hall, the police are going to come with their guns out," he said. "Until they find out if there's a gun or not, they're going to put people on the ground and search people."
Still, he said, there are "very few circumstances" that would justify police kicking people on the ground.
