Mild symptoms are being reported after three people were exposed to bear spray.
According to Windsor police, officers responded to a weapons call late Sunday night in the 2200-block of Dougall Avenue.
When officers arrived, they found two men and a woman dealing with mild symptoms consistent with bear spray exposure.
Police talked to the individuals and learned a person was talking to two occupants seated in a parked vehicle, when an unidentified person approached and discharged a noxious substance, believed to be bear mace, in their direction.
Investigators say the male suspect fled the area on foot and is described to be around 15-years-old.
He was wearing dark clothing at the time of the incident.
The victims were treated on scene by paramedics.
Police are asking residents in the area to check their dash-cam or surveillance footage between 10:30 p.m. and 11:30 p.m. on May 11.
