Two men were threatened at knifepoint as they walked along a Kettering street last night (Tuesday).
Police were called at about 11.40pm after the victims were approached by two men who got out of a parked red Volkswagen Golf in Lake Avenue.
The offenders demanded the men empty their pockets and when they refused, they drew a knife.
The victims managed to run away and suffered no injuries.
Police are appealing for witnesses to the incident, and anyone with information should contact them on 101 or Crimestoppers on 0800 555111.
