A 29-year-old man has been arrested in connection with the stabbing of a security guard at a Winnipeg Dollarama on Tuesday afternoon.
Authorities say a suspect entered the store on Portage Avenue – at the Courts of St. James – around 4 p.m. and was confronted by the 22-year-old guard about possible shoplifting.
When the security guard asked the man to leave, he was stabbed in the upper body, according to Winnipeg police. The suspect is said to have fled with stolen merchandise.
The security guard, whom CityNews learned worked for Impact Security, was seriously injured and taken to hospital in unstable condition. He was later upgraded to stable.
Winnipeg police say they distributed a bulletin with a suspect description, and that led to an arrest near Portage Avenue and Strathmillan Road just before 10 p.m. Police say the suspect was spotted by an off-duty patrol officer, who contacted on-duty staff.
Nelson Preston Sumner has been charged with aggravated assault, robbery, and failing to comply with probation order. The allegations against him have not been tested in court.
