Two robbers attacked security guards as they delivered cash to a building society in Blaby early yesterday (Monday) morning.
The men targeted the two guards as they arrived at the Nationwide branch in Enderby Road, at 6.20am.
The robbers, whose faces were covered by balaclavas, threatened the guards before hitting one of them on his head.
They escaped with a cash box. The sum of money in the box has not been revealed.
They ran to the Waitrose car park nearby and fled in a car. Paramedics treated the injured guard at the scene.
The two robbers were wearing dark clothing.
Detective Constable Grover Campbell, the investigating officer, said: "Thankfully the guards in this case were not injured, but were understandably left shaken and upset.
"We are now doing all we can to locate those responsible and hope that members of the public will be able to help us.
"We are currently gathering all the information we can about the incident and potential weapons used by the offenders, however we do know that they did not use firearms.
"In order for us to get all the information possible we need to speak to witnesses and anyone with information.
"We are particularly keen to speak to a man who was jogging in the area at the time of the robbery.
"He was wearing a high visibility jacket and we believe that he may be able to help us with our inquiries.
"If you have any information that can help us with our investigation please call us immediately."
