PHILADELPHIA (CBS) — Philadelphia Police are investigating a wave of vandalism to dozens of parked cars in the Fairmount and Chinatown sections of the city overnight.

Police say under the cover of darkness, vandals drove up and down streets smashing windows of parked cars.

A patrol officer discovered discovered the first damaged cars in the 1800 block of Poplar Street just before 5 a.m.

As residents began waking up to take their children to school or head to work, they discovered driver’s side windows shattered, or back windows smashed.

Police say nothing appears missing from the vehicles and mischief may have been the motive.

Investigators also found damaged car windows in the 600 to 700 blocks of North 25th Street; the 2200 to 2500 blocks of Parrish Street and the 1800 block of Parrish Street.

Investigators hope video from a surveillance camera in one of the neighborhood captured an image of the vandals at work.
