The octogenarian ex-professional acted instinctively to punch his attackers nose when confronted with a 10-inch knife, with a curved blade, whilst walking along Colville Road, Cambridge, on Wednesday, January 4. The mugger, described as white, slim, 18-20, stumbled backwards and dropped the knife after the 84-year-old landed the deft blow. The knife was picked up before the mugger, wearing a light jacket with a dark collar turned up, dark trousers and white trainers, ran off towards Cherry Hinton High Street. DC Sam Constable said: The victim was scared and reacted instinctively and bravely by punching the robber. I would ask anyone who was in the area at the time to consider whether they saw this happen or the mugger leaving the scene. INFORMATION: Anyone with information should contact DC Constable on 101 or Crimestoppers, anonymously, on 0800 555111.
