At 10.15pm on Monday 20th September 2014 a man entered the Shell service station in Nashleigh Hill, Chesham and pointed what is believed to be a gun or an imitation gun at staff, demanding money.
No money was available from the till, so the man left empty handed. No one was injured during the incident.
The offender is white, 6ft and of medium build. He was wearing a black jacket, a grey hooded top under the jacket, grey jeans, black shoes and a balaclava.

Incidents of this nature are rare in Chesham and officers are in the process of carrying out house-to-house enquiries in the area and investigating the circumstances.‘
