The Special Investigations Unit (SIU) has now been called in to investigate. SIU spokesperson Monica Hudon told reporters in Aurora Thursday morning that four officers were involved in the shootout.

“The male was struck multiple times and pronounced deceased at the scene,” Hudon said.

“One officer suffered minor injuries and was taken to hospital for treatment.”
