WASHINGTON (AP) — The city of Cleveland has reached a settlement with the U.S. Justice Department over a pattern of excessive force and civil rights violations by the police department, according to a senior federal law enforcement official.

The official was not authorized to speak publicly of the settlement ahead of the official announcement, expected this week, and spoke on condition of anonymity. The specifics of the settlement were not available Monday.

News of the settlement comes two days after a white police officer was acquitted of manslaughter for firing the final 15 rounds of a 137-shot police barrage through the windshield of a car carrying two black, unarmed suspects in 2012.

The suspects' backfiring vehicle had been mistaken for a gunshot, leading to a high-speed chase involving 62 police cruisers. Once the suspects were cornered, 13 officers fired at the car.

The chase prompted an 18-month Justice Department investigation. In a report released in December, the department required the city to work with community leaders and other officials to devise a plan to reform the police department, which a judge must approve and an independent monitor will oversee.

Justice Department spokeswoman Dena Iverson did not return messages seeking comment. Messages to a Cleveland city spokesman and the police department seeking comment weren't immediately returned Monday evening.
