Police hunting for a violent prisoner who went on the run after being sprung from the clutches of two prison guards as they escorted him to hospital have released CCTV images of his armed escape. Forces nationwide have joined the search for Andrew Farndon, who made the 'planned' escape as he arrived at West Suffolk Hospital in Bury St Edmunds, Suffolk, for treatment on Wednesday. It is understood that Farndon, whose family lives in the Coventry area, inflicted a serious knife wound on himself at Highpoint Prison in Stradishall, near Newmarket, before being taken to the hospital in a taxi accompanied by the guards. When they arrived, a waiting gunman confronted the male and female prison officials, before fleeing with Farndon across the car park.
