Thames Valley Police is appealing for witnesses following an aggravated burglary at a Reading forecourt.
The incident occurred on October 3 at the BP Garage on the A33 at about 10.30pm.
Four masked men, described as being in their mid twenties, entered the garage and took an amount of cigarettes and money from the till. The men then left the scene.
It is believed that a blue Mercedes, which was seen parked close to the scene of the incident, could have been used by the offenders.
Officers also believe that a dark coloured Audi A3 or A4 could also have been used by the offenders.
Investigating officer PC Benjamin Rimmer, of Reading Force CID, said: “We would like to speak to anyone who believes they have any information relating to this incident, or who saw any of the vehicles we have described, to contact us via the 24-hour non-emergency number 101.”
