A SECURITY guard from Harrow was shot in the leg during an armed robbery at a supermarket in Hertfordshire.

The 46-year-old victim was injured shortly after 7.30am yesterday (Tuesday) along with a second man outside Tesco in Tring and remains in a stable condition in hospital.

Police believe he worked for Group Four Securicor and was making a delivery from a van when the robber approached him on foot and attacked him, and a gun went off.

A member of the public who intervened - a 33-year-old man from Hemel Hempstead, Herts - was also shot in the leg. Both he and the security guard were taken to Stoke Mandeville Hospital in Aylesbury, Buckinghamshire.

The robber fled the scene with another man on a P-reg Triumph motorcycle which they abandoned nearby when they transfered into a second getaway vehicle.

The duo got away with the security guard's cash box. Police are refusing to disclose the amount of money contained inside or whether it has been recovered.

Detective Chief Inspector Mick Hanlon, of Bedfordshire and Hertfordshire Police's Major Crimes Unit, said: "This was a pre-meditated and pre-planned attack which has resulted in two men receiving serious gunshot wounds.

"We are treating this incident extremely seriously and I would urge anyone with information, or who may know who those responsible are, to contact us immediately."
