Sawyers, who has 79 previous convictions, 27 of which are for burglary, swore at officers and called them “pigs” as they drove him to hospital.Earlier he had broken into the offices of Japanese bank Shinkin International in Moorgate, and stolen lunch vouchers worth £1,000.He then broke into the offices of Bravo Solutions, also in Moorgate, where he took four laptops and two laptop bags.Several hours earlier he had stolen a mobile phone from the manager’s office of Poundland in Stratford.Just days earlier, Sawyers had been handed a 12-month sentence suspended for two years for burgling the Mayor’s office in Lambeth Town Hall, Brixton, after smashing down an original grade two listed door.

Lambeth Town Hall, where Sawyers stole from the MayorCredit:PA Mr Amin, mitigating, said: “He injured himself, in fact walking into a lamppost, suffering a significant gash to his head.”Despite the suggestion that he leads a chaotic lifestyle his mother is in court today which is unusual. These are not particularly sophisticated offences.”He is a man who is crying for help and I urge you, my lady, to give him one more chance by not invoking the suspended sentence.”Sawyers, who suffers from bipolar disorder and has a ‘long-standing’ addiction to heroin and crack cocaine, wants to turn his life around and become a forklift driver, said Mr Amin.The burgler pleaded with the judge from the dock, saying that he wasn’t a “hopeless” case.”It doesn’t sit right with me that, you know, I’ve chosen this lifestyle, and that I’m very sorry,” he said.”I just plead with you, your honour, have it in your mind to hopefully realise this opportunity.”But Judge Munro did not take pity on the career criminal, jailing him for 16 months, telling Sawyers: “You were found lying in the street having suffered a head injury with the stolen property lying beside you.”You were clearly under the influence, you say, of prescription drugs and you were aggressive when you were taken to hospital. “As you said to the prosecutor earlier on, thefts of this sort of item can result in a very very significant loss to their users.”Fortunately for these victims and for you all the property was in fact recovered. In addition of course I am dealing with not one but three commercial burglaries committed on the same day.”Your mother still supports you and you should be grateful for that. I am satisfied too that you are an articulate man who could do a lot better than what you are now.”Sawyers, of William Morley Close, East Ham, east London, admitted three counts of burglary.
