Police killer Harry Roberts has been released from prison, it has been revealed.
The 78-year-old, who was jailed for life for shooting dead three unarmed policemen in 1966, was released from Littlehey prison in Cambridgeshire on Monday night, The Sun reported.
A spokesman for the Ministry of Justice said: “We do not comment on individuals.
“Offenders on life sentences are subject to strict controls for as long as their risk requires them. If they fail to comply with these conditions they can be immediately returned to prison.
“Offenders managed through multi-agency public protection arrangements (Mappa) are monitored and supervised by probation, police and other agencies.”
Roberts was behind bars for 45 years after murdering Detective Sergeant Christopher Head, 30, Detective Constable David Wombwell, 25, and Constable Geoffrey Fox, 41.
The revelation he was to be released sparked anger from police and politicians last month.
