Ontario’s police watchdog is investigating after a man died after being driven home from a Grand Bend bar by an OPP officer.

The officer drove the 52-year-old man home from the Gables in the Bend on Main Street around 2:30 a.m. Sunday, said OPP Sgt Dave Rektor.

The man, who hasn’t been identified, was left in the care of someone, Rektor said. Two hours later OPP were called back to the home after he went into medical distress. He was pronounced dead at 5 a.m.

One officer is the subject of the investigation, while a second officer has been designated a witness, said the SIU, who have assigned six investigators to the case.

The SIU investigates cases of civilian injury or death involving police.
