A MAN who has notched up 16 convictions in the past 30 years was jailed for nine months yesterday for attempted burglary and theft. Yip Kim-kwok, 59, had pleaded guilty before Magistrate Fergal Sweeney. Mr Sweeney noted that Yip had been a professional burglar since he was 16. Eastern Court heard Yip was arrested after being seen leaving the back of a Wan Chai restaurant on April 2 and had said under caution he entered the restaurant, but had not stolen anything. Yip admitted earlier stealing two crowbars, a metal hook and a screwdriver from a Johnston Road stall. Counsel, R. P. Sabaratnam, said Yip had tried to get money for his ill mother.
