Old Orchard Beach police are investigating a series of burglaries of homes and cars that have occurred in one section of town since Saturday.

The person or people who have committed the break-ins appear to be targeting unlocked homes and vehicles where valuables are left within plain view of a window, said Detective Sgt. David Hemingway on Wednesday.

The burglaries almost all happened over last weekend and were committed very late at night or early in the morning, he said. In some cases, residents were home asleep when the residential burglaries happened.

There were five residential burglaries and about 10 vehicles that were broken into, some parked in driveways and some on the street, he said.

The burglaries were concentrated in the area of Ocean Park, Union Avenue, and the beach side streets of West Grand Avenue and East Grand Avenue.

The thieves have stolen purses, electronics, jewelry and money, he said.

Police ask residents to report any suspicious activity and to lock their homes and vehicle doors.

Anyone with information should call 934-4911 or 911 if it is an emergency.
