CLEVELAND (AP) — A Cleveland police officer who was disciplined for his role in the fatal shooting of 12-year-old Tamir Rice has seen his suspension cut in half.

Cleveland.com reports documents released Tuesday show an arbitrator has reduced Officer Frank Garmback's suspension from 10 days to five.

Garmback was disciplined for driving too close to Tamir just seconds before the boy was killed.

Arbitrator Daniel Zeiser wrote in his April 4 opinion that the city incorrectly categorized Garmback's disciplinary proceedings.

Zeiser says Garmback was placed in the Group III category, which is normally reserved for excessive use of force or officers who steal while on the job.

Garmback's partner Officer Timothy Loehmann was fired for shooting and killing Tamir outside a recreation center in November 2014.
