An armed robber threatened a Tesco Express worker and injured a child as he made his getaway from the store in Kingswood.
The incident happened at 5.25pm on Tuesday 14th January when a member of staff at the Tesco Express in Westons Way saw a man hiding toiletries in the lining of his coat.
He challenged him, at which point the suspect pulled out a knife before running out of the door. As he was leaving, he barged past a woman with a child and a pram, injuring the child who hit her head on a stand.
CCTV inquiries have identified someone who police believe might have information about the incident.
