IMAGES of people police want to speak to in relation to two armed robberies last year have been released today.

The pictures show people officers think may have vital information in raids on a petrol station in Amersham and a Tesco store in Wooburn Green.

The first hold-up was at a BP petrol station in White Lion Road, and happened at around 3pm on November 27.

One man with a handgun approached two security guards delivering and grabbed a black bag filled with cash they were delivering to the garage.

He then ran off on foot with another man, whilst a third suspect drove off in an Audi A6 towards The Chalfonts.

The second robbery happened in the evening on December 23 outside a Tesco Express in The Green, Wooburn Green.

A man with a black handgun went up to a security guard who was there to stock up the cashpoint and said “Give us that box if you know what’s good for you”, before taking a blue cash box full of cash.

He then got into a silver car waiting nearby which sped off.

Anyone with information on these men can contact Thames Valley police on 0845 8 505 505, or Crimestoppers anonymously on 0800 555 111.
