The Owen Sound Police Service is investigating an incident at the Family Health Team strike Thursday afternoon.
Strikers allege a woman entering the property through the south entrance off 1st Avenue West failed to stop her vehicle and hit a picketer, causing a small abrasion to his shin.
It is further alleged that the strikers retaliated by pounding on the vehicle, resulting in a broken windshield and several dents.
Police are asking anyone who witnessed this event to contact the Owen Sound Police Service.
It's the latest in a series of altercations at the Family Health Organization picket line in Owen Sound.
In the last two weeks, several people have been bumped or hit by cars or trucks and suffered injuries.
On August 23, a man drove up to the picket line, revved his engine, then released his brakes, scattering the picketers in front of him. The vehicle rolled over the foot of one woman, breaking it in three places.
