A gunman opened fire on a crowd of people in Cleveland early Sunday, wounding nine before fleeing the scene.

Officers on duty in the city’s historic Warehouse District responded at about 2:30 a.m. and provided medical aid, Police Sgt. Jennifer Ciaccia said in a Facebook post. The victims were rushed to a local hospital; their conditions were not available but no fatalities were immediately reported, she said. No arrests had been made.

“Investigators are in the process of reviewing evidence and video, as well as interviewing victims at MetroHealth Medical Center,” Ciaccia said. Police did not immediately respond to USA TODAY’s request for additional information.
