Police are releasing a surveillance image of a possible witness to an armed robbery in Portsmouth.

A man had entered the shop minutes earlier and demanded money from two members of staff while carrying what appeared to be a knife.

Staff handed over money from a safe before the robber locked them in a room inside the shop while he left with a quantity of money. No-one was assaulted or injured during the robbery, but the women working in the shop were shaken by what happened.
An investigation by detectives from Portsmouth CID is continuing.
