A robber jumped over the counter at a Bury St Edmunds convenience store and threatened staff with a knife on Wednesday night.

The incident happened at the Co-op in Out Risbygate and police are appealing for any witnesses - or anyone driving in the vicinity around the time who has a dashcam in their vehicle - to come forward.

A man entered the shop around 7.20pm and jumped over the counter and demanded money before producing a knife.

He then stole cash out of the till before leaving the shop and was seen running away from the Co-op up Albert Street and turning left into Princes Street.

No-one was harmed during the incident.
