North Haven police are asking residents to lock their cars after a video shows a group of thieves riffling through vehicles.
The home surveillance video purportedly shows six suspects on Jan. 4 open two out of three cars in the driveway outside the North Haven home on Pool Road. The third car was locked and the suspects did not get inside.
North Haven police said there have been more than 250 reports of theft from unlocked cars in 2017.
The video has been viewed more than 10,000 times on the North Haven Police Facebook page.
"We are not saying locking your car solves all problems, but it will stop these guys from stealing from you," officers said in the post. "There have been a few comments regarding suspects breaking windows if the doors are locked, or keying your car. That is not the case, and has not been so for a very long time. Criminals have been checking the doors to see if they are locked."
