BOULDER, Colo. –

Boulder police are investigating several reports of vandalism to cars in the 3400 block of Colorado Avenue.

It appears someone walked on top of nine cars between 10 p.m. Friday and 6 a.m. Saturday, causing about $8,000 worth of damage, Boulder police spokeswoman Sarah Huntley said.

One person who reported damage showed officers “large shoe impressions” and dents on the roof and hood of the car, Huntley said, and police found similar damage to nearby vehicles.

No one has reported witnessing the vandalism, and police have no suspects. Anyone with information can call Boulder police at 303-441-3333.
