In the latest images from Tuesday afternoon, the suspect is pictured robbing the Independent Bank on Southfield Road near 14 Mile Road. He is holding a pistol while the clerk hands over cash in a bag. Police did not say how much money he got away with.
Officials said the same man robbed the 7-Eleven store on 11 Mile Road in Madison Heights on Dec. 18. Two days later, he allegedly robbed the PNC Bank in Madison Heights, and on Christmas Day, he robbed a PNC Bank in Royal Oak.
Police say it appears the robber wore the same black pants, black coat, black ski mask and hat with a small brim during every robbery. This time, he's also wearing a shirt and tie.
Because of the similarities, police said they believe they have a serial robber on their hands.
Anyone with information should contact the FBI Detroit Division at 313-965-2323 or police in Oakland County. A $2,500 reward is being offered to anyone with information leading to an arrest.
The suspect is seen outside the bank.
