Several Connecticut police departments are working to track down the person who robbed at least 10 banks throughout southwestern Connecticut.

Police in Westport, Norwalk, Darien and Stamford say the robberies were most likely committed by the same person. Officers believe surveillance photographs taken from different banks are of the same man.

Fairfield Police Sgt. Jim Perez says the man appears to have a subtle disguise in each committed robbery, according to surveillance.

Sgt. Perez adds that the man typically works with someone else who drives the getaway car.
