Around 11 a.m. on Sunday, employees of Millennium Place in Sherwood Park, east of Edmonton, contacted police when a 42-year-old man entered the facility for help after being pepper sprayed in the parking lot outside.
He was located in a nearby washroom attempting to rinse the contaminant from his face.
Mounties in Strathcona County determined the attack followed an alleged road rage episode involving the man and a woman driving in separate vehicles on Highway 16.
Strathcona County RCMP Const. Wally Henry said the man was followed by the woman to Millennium Place, where she confronted him after dropping off his wife and two kids.
After a brief verbal exchange, police say the man was attacked with bear spray.
Henry said he tried to run away, but was pursued and sprayed a second time. The woman then got back inside her vehicle and left.
"We've dealt with situations where someone will follow someone. But to go to this extent ... with deploying the pepper spray twice on this guy, that's a pretty extreme reaction to have," said Henry.
The woman was arrested without incident on Monday in Edmonton.
Julia Richard, 32, is charged with two counts of assault was a weapon, possession of a prohibited weapon, carrying a concealed weapon, uttering threats, possession of a weapon dangerous to the public peace and breach of recognizance.
