A masked man threatened a shop worker with a knife and a screwdriver during a late night robbery yesterday.
On February 26, a man entered a petrol station shop on the M1 Southbound in Newport Pagnell and demanded money from the cashier, whilst threatening him with the weapons.
The offender stole 12 packets of cigarettes before leaving the premises.
It is believed a second man waited outside whilst the incident took place.
The offender is described as white, about 6ft, of medium build.
He was wearing a ‘mask’ made from clothing, a dark “heavy hooded” jumper with a white motif on the top left and dark footwear with a light stripe on the heels.
His clothing was described as ‘mud stained’.
The cashier, a man in his thirties, was not injured.
Detective Constable Paul Wilson, said: “We are appealing to anyone who may have witnessed this offence or who may have been offered any cigarettes for sale which they are suspicious of to please come forward.
