Two men suspected of attacking a security worker in Cambridge and stealing thousands of pounds have been filmed on CCTV.
The security guard was attacked on Tuesday at about 1500 BST as he was picking up a cash box from Ridgeons builders merchants in Nuffield Road.
His two attackers made off in a dark blue Volkswagen Polo which turned on to Milton Road and then on to the A10.
It was seen later being parked in Ely opposite the One Stop shop in West End.
Both men were seen walking away from the vehicle towards St Mary's Street and Cambridge Road.
Police have released CCTV stills of the men they want to trace.
Det Con Matt Bailey said: "I am appealing for anyone who was in the area when this robbery happened to consider if they saw the men described or anything suspicious.
"We know there were people in Ely when the car was abandoned and we have not yet recovered the cashbox."
