A CASH box was stolen from a security guard during a robbery at a Tesco in High Wycombe this afternoon.

Police scrambled a helicopter to search for a car which left the store and petrol station on Amersham Road at 1.04pm following the incident.

The security guard was not injured in the attack, police said.

Details about the car, a description of the attackers and how much cash was taken is unclear at this time, as the incident is ongoing.

More details to come as we get it.
