Winnipeg police say a group of people were attacked with bear spray at The Forks on Sunday evening.
Just before 6 p.m., three people were sprayed with the then-unknown substance. A 12-year-old boy, 15-year-old girl and 18-year-old woman were treated in hospital and released.
Police believe three suspects approached the victims, who were unknown to each other, and sprayed the repellent at them.
A 17-year-old Winnipeg boy has been charged with several offences, while two suspects remain outstanding.
Police continue to investigate.
