Two men attacked a security guard and stole cash in a robbery at a Stafford petrol station.
The offenders, wearing motorcycle helmets, struck when the security guard transporting the money stopped on the forecourt of the Esso petrol station, on Lammascote Road.
The robbers pulled up on a Honda 500 CB motorbike, and the passenger jumped down and attacked guard before taking a quantity of cash.
He is white and in his 20s, wearing a black coat, black tracksuit bottoms with a white stripe and trainers.
He also wore a black full-face motorbike helmet with a distinctive oval logo on the back.
The motorbike rider was wearing a grey coat and a dark-coloured full-face motorbike helmet.
The security guard was not injured but is badly shaken.
The motorbike, registration BX51 MFU, was later recovered off Riverway on the cricket and hockey club car park, opposite the White Eagle Polish club.
Earlier, it had been seen near the Hough Retail Park just before the incident at 1.15pm on Saturday (October 19).
Officers are keen to speak to anyone who saw a silver and red Mitsubishi Shogun which drove through a red light on Riverway and turned left onto the A34 towards Cannock.
It was driven by a man described as being white with a shaved head and two other men were in the vehicle.
Anyone with any information is urged to call Staffordshire Police on 101 quoting serial reference 397.
