The 45-year-old was getting out of his lorry after parking in a layby in Sutton Road, Haddenham, and was attacked from behind. He suffered serious but not life-threatening injuries in the attack and was taken to Addenbrookes Hospital, Cambridge. The attacker is described as white, 6ft-tall, medium build and wearing dark clothing. It is believed he may have fled the scene in a vehicle. Detective Sergeant Phill Richardson said: The road would have been busy at the time of this assault and I would urge anyone who witnessed the incident to contact police. The lorry is very distinctive with the word Savage on the side and I would like to hear from anyone who may have seen someone hanging round this vehicle or fleeing from it. It is important we catch this man as soon as possible and we have a number of officers working on this investigation at this time. INFORMATION: Anyone with information should contact police on 101 or Crimestoppers, anonymously, on 0800 555 111.
