The province's police watchdog agency is investigating after a man set himself on fire while London police officers were present.
The Special Investigations Unit (SIU) said on Friday at around 1:30 p.m., officers responded to the Immigration, Refugees and Citizenship Canada office located at 417 Exeter Rd.
Officers arrived at the scene and attempted to communicate with a 48-year-old man who was threatening to harm himself. Two officers then fired plastic projectiles from an Anti Riot Weapon at the man who then set himself on fire.
Firefighters, who were already on scene, were able to extinguish the fire.
The man was taken to hospital to be treated for serious injuries.
The SIU investigates incidents involving police that have resulted in death, serious injury, or allegations of sexual assault.
