Police have launched a man hunt for a convicted murderer who has escaped from jail.
64-year-old John Massey escaped from Pentonville Prison in Islington, North London at around 6:30pm yesterday evening.
Scotland Yard said he is considered "potentially dangerous" and should not be approached.
Massey was sentenced to life imprisonment for the murder of a man at a pub in Hackney, East London in 1975.
A police spokesman said:
Police are appealing for help in tracing a convicted murderer who has escaped from HMP Pentonville. He is considered potentially dangerous and should not be approached by the public if he is seen.
According to reports, Massey was 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.
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, according to the Guardian.
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.
Anyone with information of Massey's whereabouts is asked to call Islington Police on 020 7421 0296, or people can inform Crimestoppers anonymously on 0800 555 111.
