Police in western Berks County are urging neighbors to be on alert after vandals caused damage in at least two communities.
Western Berks Regional police said vehicle windows were smashed with rocks in Wernersville and Robesonia.
One man said his vehicles have been damaged before, and he's getting fed up.
"It's been probably something at least every year, so, things happen once you can understand it, maybe dismiss it a little bit, but here were are six years, and I've had all kinds of damage to two vehicles," said Jason Iswalt.
The vandalism happened between 5 p.m. and 10 p.m. Sunday, police said.
