BISMARCK, N.D. - Car break-ins can sometimes be preventable.
In the last year Bismarck has had more than 200 of them. This summer alone they've had 85.
The Bismarck Police Department says in recent weeks they've seen a rise in the south side of Bismarck by the mall and Washington Courts.
The Bismarck Police Department says a big chunk of the break-ins are from cars that are unlocked.
"It's just common sense stuff you can do to, you know, prevent it," said Todd Thilmomy, Bismarck resident.
Police call this a crime of opportunity.
Bismarck Police Department Sgt. Tim Sass said: "Some of these crimes have increased so we really like people to take that extra proactive step."
Police recommend that you take your valuables with you. But they say that if you do happen to leave them inside your car, to leave them out of sight.
In a place like your glove compartment, under the chair, or in your trunk. But, they say the most important part is locking your door.
Sass says this is something people could help prevent.
Sass says most thieves are not breaking windows or using tools to get in.
The department wants to remind people to lock their doors.
