LAKEWOOD, Ohio - A former Dunkin' employee is accused of trying to rob the same Lakewood store where he was fired over the summer for refusing to serve a Cleveland police officer disciplined for his role in the fatal shooting of Tamir Rice.

Shontay F. Brown, 30, is charged with aggravated robbery in the Saturday incident at the Dunkin' on West 117th Street near Franklin Boulevard, police said.

Brown was fired from the store in July for refusing to serve an officer in uniform. Cleveland Police Patrolmen's Association president Jeff Follmer identified that officer as Frank Garmback, who drove his police cruiser within feet of Tamir before his former partner fatally shot the 12-year-old boy on Nov. 22, 2014 outside Cudell Recreation Center.

The Dunkin' store's owner told news outlets in July that he did not believe Brown recognized Garmback, but he fired him for refusing service to a customer. Follmer said Monday that he spoke to a store manager and thanked him for the owner's handling of the situation.

Brown is accused of forcing his way into the Dunkin' just after midnight Saturday and trying to steal a safe, Lakewood police Capt. Ed Hassing said.

A Dunkin' employee heard a knock on a back door and opened it. The robber forced the employee into a freezer, then went into an office and took a safe, Hassing said.

The employee did not see a weapon, but the robber had his hand in his pocket as if he were holding one, Hassing said.

A delivery drive arrived at the Dunkin' around the same time and saw the robber pulling the safe out of the store. He called 911 to report the robbery.

The robber realized he'd been spotted and ran away before police officers arrived, Hassing said. He left the safe outside the store.

Lakewood detectives used Dunkin' security camera video to identify Brown as a suspect in the attempted robbery, Hassing said. A U.S. Marshals task force arrested Brown on Monday on Gramatan Avenue near West 140th Street in Cleveland.

A Cuyahoga County grand jury declined to bring criminal charges against Loehmann and Garmback for their roles in Tamir's shooting death. The city of Cleveland later fired Loehmann, not for the shooting, but for lying on his application when he applied for his job.

Garmback was initially suspended for 10 days using improper tactics when driving his police cruiser to within feet of Tamir, and for failing to notify dispatchers when he arrived at Cudell Recreation Center. An arbitrator later reduced the suspension to five days.
