first major fire broke mid-afternoon in a grocery store at the corner of 12th Street and Atkinson. The crowd prevented firefighters from extinguishing it, and soon more smoke filled the skyline. Local responses The local news media initially avoided reporting on the disturbance so as not to inspire copy-cat violence, but the rioting started to expand to other parts of the city, including looting of retail and grocery stores elsewhere. By Sunday afternoon, news had spread, and people attending events such as a Fox Theater Motown revue and Detroit Tigers baseball game were warned to avoid certain areas of the city. Motown's Martha Reeves was on stage at the Fox, singing "Jimmy Mack," and was asked to tell people to leave quietly, as there was trouble outside. After the game, Tigers left fielder Willie Horton, a Detroit resident who had grown up not far from 12th Street, drove to the riot area and stood on a car in the middle of the crowd while still in his baseball uniform. Despite Horton's impassioned pleas, he could not calm the crowd. Mayor Jerome Cavanagh stated that the situation was "critical" but not yet "out of control." At 7:45 p.m. that first (Sunday) night, Cavanagh enacted a citywide 9:00 p.m. – 5:30 a.m. curfew, prohibited sales of alcohol and firearms, and informally curtailed business activity in recognition of the serious civil unrest engulfing sections of the city. A number of adjoining communities also enacted curfews. There was significant white participation in the rioting and looting, raising questions as to whether the event fits into the classical race riot category. July 24 Police crackdowns Michigan State Police and the Wayne County Sheriff's Department were called in to Detroit to assist an overwhelmed Detroit police force. As the violence spread, the police began to make numerous arrests to clear rioters off the streets, housing the detainees in makeshift jails. Beginning Monday, people were detained without being brought to Recorder's Court for arraignment. Some gave false names, making the process of identifying those arrested difficult because of the need to take and check fingerprints. Windsor Police were asked to help check fingerprints. Police began to take pictures of looters arrested, the arresting officer, and the stolen goods, to speed up the process and postpone the paperwork. More than eighty percent of those arrested were black. About twelve percent were women. Michigan National Guardsmen were not authorized
