"These people woven in and out of moving and parked vehicles, threatened motorists and pedestrians, when Sergeant Bourque fought," police said in a statement.
Bourque was treated and released from Vanderbilt Medical Center, according to a tweet from the department.
The 22-year-old MNPD veteran was not the only person in danger of the vehicle.
"He lost control of the four-wheel and it turned over on my son's car," she told the news station. "They ran up the street, rode with another rider. A black truck pulled up, shot everything up and they just went up on their day that nothing ever happened."
"They not only put themselves in danger without innocent companions," she said.
A search is underway for the suspect who beat Bourque.
