Norwalk police are warning residents to always keep their doors locked after recent break-ins and thefts.

The Norwalk Police Department released surveillance video from a resident on Monday morning that showed two individuals attempting to break into their parked cars.

Officers recommend taking keys, fobs and any valuable items with you when you leave your vehicle.

Police say patrol officers have been actively monitoring neighborhoods to prevent more attempts and catch the responsible parties.

To report any suspicious behavior or cars, call 203-854-3000 or 911 in an emergency.
