A 22-year-old woman has been arrested after a robbery on Wednesday afternoon.

Thompson RCMP were advised that a woman had approached a 9-year-old girl who was on a bicycle and asked for the bag of food she was carrying.

A bystander saw the incident, intervened by chasing the suspect away, and brought the child to safety.

The victim and witness were able to provide an accurate description of the suspect to police and she was later located and arrested.

Judith Robinson, 22, has been charged with Robbery, Resisting Arrest and Causing a Disturbance. She has been remanded in custody.

The 9-year-old girl sustained minor injuries but did not require medical attention.
