A Toronto police officer has been charged with sexual assault after he allegedly assaulted a woman inside his police cruiser, the province’s Special Investigations Unit said Wednesday.

The SIU says the officer picked up a 27-year-old woman near Wellington Street West and Blue Jays Way last year.

Around 1 a.m. on Sept. 24, 2015, the officer drove the woman to her residence.

On the way there, he allegedly assaulted her.

Sgt. Christopher Heard is facing one charge of sexual assault and will appear in court on April 16.

The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
