The Suffolk Police Department spent Sunday responding to nearly two dozen reports of vehicle break-ins and tampering with vehicles.

Roughly half the incidents took place at homes in North Suffolk communities off Bridge Road, with most of the rest filed by residents in subdivisions off Nansemond Parkway.

Residents of Mainsail Lane, in Harbour View Estates II, filed seven reports on Sunday, four for tampering with vehicles and three alleging thefts from vehicles, according to police reports.

One resident each from Breezeport Way and Torrington Circle, in Governors Pointe, also filed reports of thefts from vehicles on Sunday.

Other related reports include:

• Two vehicles were allegedly broken into and a third vehicle reported stolen from Barn Owl Court, in Nansemond Crossing, on Sunday.
• Reports of tampering with a vehicle and theft from a motor vehicle came from separate addresses on Cherry Blossom Drive, in the Cedar Lake Shores subdivision, on Sunday.
• Two reports of tampering with vehicles on King Street were filed Sunday. Also on Sunday, two reports of tampering with a vehicle and one of theft from a motor vehicle were filed from Woodshire Way. Both streets are in the Woodshire Landing subdivision.
• One report of theft from a motor vehicle on Craftsman Circle, in the Kensington Park subdivision, was filed Sunday.
• One report of theft from a motor vehicle at Olde Mill Creek Drive, in the Olde Mill Creek subdivision, was filed Friday.
• One report of theft from a motor vehicle on Franklin Street, in the downtown area, was filed Friday.

On Monday, several North Suffolk residents said they were unaware of the rash of break-ins.

“I didn’t know about this,” said Mainsail Lane resident Gerald Johnson, as he pruned a tree in his front yard Monday. “We lock our doors, and we all try to look out for one another in the neighborhood.”

Sinclair Lewis, a resident of Harbour Breeze Apartments, said he always locks his doors.

“I’m sure once everyone hears this, they will take an extra minute to lock their doors,” he added.

Police have not made any arrests, according to city spokesman Tim Kelley.

Police are encouraging residents to always lock their car doors,

“In almost all these incidents, the vehicles were unlocked,” said Kelley. “Locking car doors helps prevent easy access to would-be thieves.”

According to Kelley, police say there are several important reasons to make locking car doors a habit.

Loss of valuables is the most obvious reason to lock your door. Unlocked vehicles with GPS devices, electronics, cell phones, money and other valuables in plain sight are easy targets for thieves.

Locking your car doors also prevent possible entry into your home. If you leave your doors unlocked with a spare set of house keys or a garage door opener in the glove compartment, it becomes easy for the someone to enter the home.

If people know you tend to leave your homes and cars unlocked and word gets around, it becomes a future open invitation for crime, Kelley said.
