Hastings-on-Hudson police say more than 10 cars were broken into Tuesday night, and all of the vehicles were unlocked at the time.

Police say the break-ins happened in the vicinity of Jefferson Avenue, Rosedale Avenue, Mt. Hope Boulevard, Ravensdale Road, and Farragut

Avenue. Police say the perpetrators aren’t breaking windows or damaging cars, they’re stealthily checking door handles.

Officials say the solution is simple: lock car doors and remove valuables.
