A notorious police killer has been released from prison after serving 48 years of a life sentence.

Harry Roberts, now 78, was jailed in 1966 for murdering three unarmed officers in Shepherd’s Bush, West London.

The Wanstead-born man was released from Littlehey Prison in Cambridgeshire yesterday and it is thought he will be closely monitored.

The Ministry of Justice said it did not comment on individual cases, but said there were “public protection arrangements” in place to manage released prisoners.

“Offenders on life sentences are subject to strict controls for as long as their risk requires them,” a spokesman said.

“If they fail to comply with these conditions they can be immediately returned to prison.”
