A man was convicted today of holding two prison officers at gunpoint to help an inmate jailed for a violent assault escape custody.
Garry Cowan, 45, was found guilty of springing Andrew Farndon from outside the West Suffolk Hospital in Bury St Edmunds on January 25.
The getaway took place after Farndon was taken to the A&E ward with a knife wound sustained at Highpoint Prison in Stradishall, Suffolk.
Farndon was serving an indeterminate sentence after fracturing a victim's skull in a hammer attack. His escape sparked a nationwide manhunt.
Cowan, his former jailmate, had been released 15 days earlier after serving a 9-year sentence for robbery.
He denied possession of a replica firearm with intent to cause fear of violence, and assisting an offender to escape.
But a jury in London found him guilty on both counts.
