B.C.’s police watchdog is investigating after a police car struck and seriously injured an elderly woman in Chilliwack on Friday.

The woman was crossing Tyson Road near Cumberland Avenue at about 5:30 p.m. on Friday when the police car hit her, the Independent Investigations Office of B.C. said in a statement. 

The IIO could not confirm the car’s speed or whether the woman was in a marked crosswalk.

“Those details will be the subject of our investigation,” said Ron MacDonald, the IIO’s chief civilian director.
