Police have released clear pictures of a man who is believed to be involved in three bank robbery cases.
The man attempted to rob a People's United Bank in Huntington Tuesday morning, but he ran off when the teller refused to hand over the money.
Police say about 25 minutes later, the suspect successfully robbed a TD Bank on Deer Park Avenue.
A week prior, the same man allegedly robbed a TD Bank on Broadhollow Road in Farmingdale.
Anyone with information about the suspect is asked to call Suffolk Crime Stoppers at 1-800-220-TIPS.
