A good Samaritan with a camera helped in catching an off-duty Detroit Police Officer and his former DPD accomplice, who were involved in a pistol-whipping and robbery outside a Citgo gas station. It was originally thought that the men conducting the robbery were impersonating police officers. Then, according to DPD Chief James Craig, "Several unidentified police officers were working this particular robbery case, recognized one of the suspects in the photographs as being a member of the Detroit Police Department."

According to WJBK, now under arrest are two police sergeants, a 47-year-old officer and 20-year veteran of the Detroit Police Department and his 42-year-old buddy from the police academy, who is a former DPD cop and 17-year veteran of the St. Clair Shores Police Department. The latter recently received a distinguished service award.

"In fact, they were police officers, just not working on-duty at the time," Craig said. One of the alleged victims identified the St. Clair Shores sergeant from a photo lineup.

It is alleged the two sergeants pulled up in a black pickup, got out of the truck with their guns drawn and their badges around their necks, detained two young men in their early twenties, searched them and pistol-whipped one of them, stealing his wallet and cell phone. The other alleged victim told police they also stole his money.
