Murderer escapes over prison wall
A "potentially dangerous" murderer has gone on the run for the third time after escaping over the walls of Pentonville Prison using a makeshift rope.
John Massey, one of Britain's longest-serving prisoners, made off from the category B jail in Islington, north London, at around 6.30pm on Wednesday.
The 64-year-old used a makeshift rope to escape over a wall and was not spotted in time by prison officers, sources said.
The convicted killer was sentenced to life imprisonment for shooting a man dead with a sawn-off shotgun at a pub in Hackney, east London, in 1975.
An investigation into how he managed to elude staff is under way by the Prison Service.
Massey was initially released on parole in June 2007 after spending the last 18 months of his life sentence in an open prison in Derbyshire preparing for freedom, it is understood. Under his parole terms, he was ordered to live in a bail hostel in Streatham, south London, under a curfew.
After several months, he broke his curfew and spent a number of days living with his dying father. He was immediately recalled to prison but decategorised after two-and-a-half years before being sent to Ford open jail in West Sussex.
Massey reportedly walked out of the prison after hearing news that his sister was gravely ill. He was rearrested 10 months later and taken to Pentonville before his latest escape.
Scotland Yard has advised members of the public not to approach the "potentially dangerous" offender and instead to call 999 if he is spotted.
Pentonville houses up to 1,250 category B male prisoners, rather than the most serious category A offenders. Category B prisoners are described as those "for whom the very highest conditions of security are not necessary but for whom escape must be made very difficult".
