POLICE have released CCTV footage of the terrifying moment when staff at a Hampshire convenience store were confronted by a gunman.

Two workers were opening up the Tesco Express in Watson Walk, Totton when a man wearing a hooded top entered the shop and produced a firearm.

The robber bundled staff into the shop's toilets during the frightening ordeal and made off with cash and cigarettes.

Detectives have now released footage of the incident, on March 7 this year, as they step up their investigations.

Tesco has offered a £2,500 reward for information leading to a successful conviction.

Detective Sergeant Martin Myers said: "This man would have been carrying a large clear polythene sack containing boxes of cigarettes. We know he did not get in a vehicle and walked away from the store.

"I would urge anyone who may have seen a man carrying a large sack or has any information which may assist us in identifying him to contact us."

A 31-year-old man from the Totton area has been arrested in connection with the robbery and is on police bail pending further enquiries. He is due to report back at Lyndhurst police station in June.
