The Oakland County Sheriff's Office wants to remind residents to lock their vehicles and leave nothing valuable inside for criminals to take. The majority of vehicle thefts and larceny from vehicles are a result of them being left unlocked. Double-check every time you get out of your vehicle that you locked it.
Also if you see something suspicious, say something. The City of Rochester Hills substation can be reached at 248-537-3530 or call 9-1-1 in the case of emergency.
