Ontario’s Special Investigations Unit is probing the details of the death of a 52-year-old man in Kingston Tuesday afternoon.

The SIU said in a news release that Kingston Police were called to Harvey’s restaurant at 890 Princess St. at about 1:30 p.m. in regards to a man’s behaviour. Police were called to assist Frontenac Paramedics at the scene, Kingston Police confirmed.

Frontenac Paramedics said that they would not be sharing any information about the call at this time.

The SIU said that when the officers arrived, they found the man in the restroom area and took him into custody. He was then taken to Kingston General Hospital where he vital signs became absent and he was later pronounced dead, the SIU said.

The SIU has assigned three investigators and one forensic investigator to this incident.

At this time, two Kingston Police officers have been designated subject officers, which means their conduct may have caused the death, according to the SIU. Four others are witness officers, an officer who was involved in the incident but who is not the subject officer.

The post-mortem will take place Thursday morning in Kingston.

“The SIU is urging anyone who may have information about this investigation to contact the lead investigator at 1-800-787-8529. The Unit is also urging anyone who may have any video evidence related to this incident to upload that video through the SIU website.”

The SIU is a watchdog agency that investigates whenever a person is sexually assaulted, seriously injured or has died while interacting with police in Ontario.
