Twenty cars were damaged in two separate acts of vandalism last week, police reports show. 

Police believe one individual is responsible for deflating at least one tire from all 20 cars by either puncturing or slashing the tires with an unknown tool.

On Aug. 20, residents in the 10300 block of Malcolm Circle reported 10 cars that had at least one tire punctured overnight. 

Ten more cars were discovered with a single slashed tire on Aug. 21, in the unit block of Cedar Tree Court. 

The neighborhoods are less than a half mile away from one another.
