LETHBRIDGE, Alta. - Police say a three-year-old girl was sitting in the back seat of a car when officers in southern Alberta made a drug arrest this week.

Lethbridge regional police and RCMP officers were taking part in an operation targeting street-level sales of fentanyl, a highly addictive and deadly opioid.

Moments after witnessing the completion of a deal, with the toddler in the back seat, police intervened and arrested two women.

The women, who are 25 and 26, cannot be identified because that could identify the child.

A vehicle search found 27 fentanyl pills and a small amount of crack cocaine.

The women are facing charges under Alberta's Drug-Endangered Children's Act.
