A convicted burglar who tricked police into letting him out of prison was "sprung" from a police car during a violent armed assault in a Birmingham street, the city's Crown Court heard.

John Davis (25) formerly of Alcester Road, Kings Heath, who admitted escape, was jailed for two and a half years by Mr Justice Gibbs, who ordered the sentence to run consecutively to the five-year sentence he was already serving.

In passing sentence, the judge said: "There was a pretence that you were going to clear up offences and help the police but instead the plan was that there would be a violent incident in which you would be released from custody."

Sara Pratt, prosecuting, said Davis, who was serving a sentence for burglary and theft, had indicated to police he wished to clear up outstanding matters by pointing out various locations where he had committed vehicle offences.

She said Davis was handcuffed and taken out in an unmarked Vauxhall Corsa with three police officers. After visiting various locations they went to the Billesley area.

Davis directed them to some garages on a service road and the officers became aware of a Volvo reversing at speed towards them.

There was a slight collision, leaving the Corsa trapped against a fence, before two men wearing boiler suits and balaclavas jumped out of the Volvo armed with a baseball bat and pick axe handle and began smashing the Corsa's windows and windscreen.

Davis was shouting "this side, this side" before he managed to jump out of the Corsa and run to the Volvo, which was then driven off.
