ANDOVER — Nearly a dozen cars were broken into over a two-day period, police said.
Andover Police Lt. Eddie Guy said that since Wednesday, 11 cars have been broken into.
He said people are leaving their cars unlocked. Items visible from outside the car are being grabbed.
"People need to be more careful," he said. "Andover is a safe community, but is not immune to people breaking into cars and stealing personal items."
The car breaks have been reported in the Shawsheen Heights section of town, off Haverhill Street, York Street, Beacon Street and Chandler Road, among others.
"It's all pretty much in the same area, happening during the night." he said. "It appears the cars they are targeting are unlocked."
Stolen items include GPS units, iPhone cases and clips, a cassette adapter and tire-pressure gauges, among other items.
"These are things they saw sitting on the center console," he said. "People need to be more careful."
Guy recommended that people bring valuables inside or secure them in the car so they are not visible from outside the vehicle.
While nearly a dozen cars have been ransacked since Wednesday, he said there could have been more before that.
"That's a lot of car breaks in a short period of time," he said. "I don't know if something's going on in Lawrence on their side, too. Somebody could be floating back and forth between the two communities."
Most of the break-ins have been along the Andover-Lawrence border, near the Mt. Vernon section of Lawrence.
The last car break was reported Thursday just after 3 p.m. The car owner said his vehicle had been parked overnight, and he noticed it at 8:30 a.m. when he got up to work.
