An arbitrator has restored lost pay for four Cleveland police supervisors disciplined after a high-speed chase that ended with two unarmed suspects being killed in a 137-shot barrage of police gunfire.

The city safety director gave the supervisors unpaid suspensions ranging from 10 days to 30 days. The supervisors challenged those suspensions.

The arbitrator's Friday ruling says the city didn't prove its case. A city spokesman says an appeal is planned.

The 2012 chase involved more than 100 officers and 62 cruisers.

Patrolman Michael Brelo (BREE'-loh) fired the final shots at the end of the chase. He was acquitted of voluntary manslaughter charges last week, prompting protests in the city.

Five supervisors still face misdemeanor dereliction of duty charges for not controlling the chase. They have pleaded not guilty. No trial date has been set.
