The Chapel Hill Police Department arrested eight people for breaking and entering into vehicles between March 14 and March 27.
All of the arrests were on felony charges, and in each incident the vehicle broken into had been left unlocked or unsecured.
Police are recommending that residents lock their vehicle doors and trunks and roll up their windows when they leave their cars.
A police press release also suggests that residents part in well-lighted areas, and that drivers never leave valuables or keys inside of their vehicles.
Police also urge residents who notice suspicious activity in their area to contact 911 immediately.
