WAUSAU, Wis. A Wisconsin man upset with the Wausau parks department has found an unusual way to retaliate.

Police say the man repeatedly hung women's underwear on department vehicles while they were parked for the night.

They say he struck 30 to 50 times, hanging bras and panties of various sizes on cars.

Police say he admitted doing it after being caught on videotape. He told investigators he was upset with the parks department because an employee cutting grass at a park would blow grass onto him while he sat in a gazebo.
