We want to trace a man in connection with an incident of robbery at a Grimsby shop during which a shop worker was allegedly threatened.
It happened at the business on Farebrother Street around 7pm on Friday 29 November.
A man wearing dark clothing, a black puffa jacket with the hood up, and a scarf around his face demanded that the woman behind the counter open the till. It’s said he was holding what looked like a blade at the time.

The shop assistant ran into a back room to call the police, while the suspect stole a quantity of cigarettes and tobacco before leaving.
He was on a bike and believed to have ridden off down Patrick Street under the subway towards Hainton Avenue.
