Dozens of nails were found scattered on a road used by emergency vehicles in York County, and police believe someone intentionally dumped them there.Passersby discovered the nails Monday afternoon at the entrance to the Newberry Township municipal building."Approximately 80 galvanized inch-and-a-quarter roofing nails that appear to be painted black so that they would blend in on the roadway," Newberry Township police Chief Steven Lutz said.Lutz doesn't believe the nails were left by accident."When individuals' construction vehicles lose some type of item off their truck, it's usually generalized into one location. If they were pulling out of that entrance, you would see a trail of them, kind of like in a line," he said.The road is frequently used by township and emergency vehicles. If the nails hadn't been discovered, police said, they could have caused a flat tire and slowed response time.Police said the person responsible would face disorderly conduct and criminal mischief charges.
