A PRISONER escaped on a stolen bike to catch a cab he booked from his cell on an illegal phone.
Gary Butcher waited till midnight before going on the run — riding to a chip shop where he had arranged to be picked up.
Prisoners at the jail are trusted to behave with minimum supervision.
Butcher, 55, was given a life sentence in 1995 for aggravated burglary and indecent assault.
He admitted escaping and was ordered to serve an extra six months in jail at Derby crown court.

The lag got the cab to Coalville, Leics, paying £150 for the journey with cash he had withdrawn earlier.
His escape was only discovered when his cell was found empty the following morning.
Passing sentence, Judge Penelope Stanistreet-Keen said: “You being at large would cause consternation with the public”.
