Police are searching for a 23-year-old Ann Arbor man believed to have robbed the Check ‘N Go on Stadium Boulevard in Ann Arbor in January.

Detective William Stanford said Friday prosecutors approved a four-count warrant for James Romell Robinson this week. He’s wanted on two counts each of armed robbery and unarmed robbery.

Stanford said Robinson is considered armed and dangerous.

Police said Robinson passed a note implying he had a weapon to a clerk at the business on Jan. 11. He was given cash and demanded all the clerks turn away, forcing them to lie on the floor before he fled the store.

Investigators interviewed witnesses but were unable to find Robinson in the immediate aftermath of the robbery.

Stanford said Robinson was last seen in the Pine Lake apartment complex on Adrienne Drive earlier this week. He drives an older model Crown Victoria or Mercury marquis, Stanford said.

Anyone with information on Robinson’s whereabouts is encouraged to call Stanford at 734-323-2628 or Crime Stoppers at 1-800-SPEAK UP (773-2587). Crime Stoppers is offering $1,000 for information leading to Robinson’s arrest.
