Several Bethel Park residents woke up on Saturday to find nails strewn in their driveways.
The residents said they believe they were targeted because of their political views.
Channel 11 received several calls from people living on Carlton Road, who reported that only homes with Donald Trump signs were targeted.
Police said four homes had nails dumped on their driveways, but they don’t know who is responsible.
"It needs to end,” resident Dan Reinhart said.
Neighbors are offering a $500 reward for information that leads to the arrest of the person or people responsible.
