CLEVELAND: The Cleveland police labor union has filed a grievance with the city over the disciplining of 64 officers involved with last year’s high speed chase that left two people shot to death.

The Cleveland Police Patrolman’s Association calls the discipline “arbitrary, disparate, excessive and unreasonable” and says it’s a violation of the collective bargaining agreement.

A fleeing driver and passenger were killed when officers fired 137 shots at them in the 23-minute chase last November that involved five dozen cruisers and wove through residential neighborhoods before ending in gunfire.

No criminal charges have been filed against the officers.

The grievance was first reported by Cleveland television stations on Tuesday.
