Norwalk police have released surveillance footage of suspects believed to be involved in a string of car break-ins last week.

Police say the thieves broke into 19 cars between Friday night and early Saturday morning on the west end of Norwalk and in the Silvermine area. They say the suspects went from car to car, checking to see whether the doors were unlocked.

The men allegedly made off with spare change, cellphones and other electronics.

Detectives say they hope someone will recognize the suspects and provide information that leads to an arrest.
