An audio recording of a violent robbery which happened in south Northamptonshire has been released by the police.
The robbery at a farm near Towcester happened at the end of June this year. Officers in charge of the case have made the decision to release the audio recording after lengthy investigations in the hope it will encourage witnesses to come forward.
The incident saw a group of masked men break into the farm building and steal cash from a couple after the robbers claimed to be police officers.
Detective Constable John Cordner, who is leading the investigation, said: “This was a very nasty incident which has left the couple very badly shaken several months on.
“Crimes of this nature are fortunately very rare in Northamptonshire, but we need to track down these men to make sure they cannot target anyone else.”
The men approached the farm just after 2am on Wednesday, June 24, and banged on the door claiming to be police officers.
Once inside, they bound the hands and feet of the couple, forced them to lay on the floor and demanded to know where they kept their money.
They also hit the woman in the face, leaving her needing hospital treatment.
During the robbery, a third man waited outside the property. The robbers eventually fled after taking cash from the property.
