Vandals spray-painted more than 20 vehicles, signs and buildings Thursday night or Friday morning.
A few road signs, one garage door and the commons area of one apartment building were also spray-painted, said Aberdeen Police Capt. Dave McNeil.
Most of the reports were south of Sixth Avenue between Washington and State streets and in the Northern State University campus area. McNeil said people started reporting damage about 11:30 Thursday night, and as of 5 p.m. Friday, calls were still coming in.
Vandals used white and pink spray paint and possibly other colors as well, McNeil said. A garage door on 10th Avenue Southeast had bright pink letters on it, though other spray-painting seemed to be scribbles.
Generally, McNeil said, more than one person is involved when there's a vandalism spree.
But police aren't certain that was the case this time, he said. They have no suspects, McNeil said.
Police have noticed a high number of vehicle burglaries in the southwest part of town in the past two months or so, McNeil said. A new records management system helps the department chart reports on a map and look for trends.
Residents in the south part of town should make sure they secure their belongings and lock their vehicles, he said.
There are probably residents whose property has been damaged but who don't know it yet, McNeil said. Vandalism reports should be called into the dispatch center at
People who have information about the spray-painting vandalism or who noticed suspicious activity that night can call the dispatch center or the anonymous Crime Stoppers number at 605-626-3500.
