A judge was yesterday puzzled by a security guard's 'odd' theft of a neighbour's money box. Ordering a background report on David Leung Shing, 56, District Court Judge Bernard Whaley said he hoped to get to the bottom of the case before sentencing on October 23. Leung pleaded guilty to burglary. The court heard he went into the storeroom of neighbour Then Njat-fa in Hang Mei Tsuen, Yuen Long, and was seen by her six-year-old son leaving with the money box - containing coins worth HK$80. Prosecutor Irene Fan said Leung saw the box, a special edition issued by 7-Eleven, while helping Ms Then remove furniture on July 12. On July 16 Ms Then's son, Tang Ka-hei, was at home alone when he saw Leung enter their house and go into the storeroom. Leung left with the box behind his back. In a search of Leung's home, the box was found in a bag on top of a wardrobe. The coins were gone. Judge Whaley said it was 'very strange' that Leung would steal a box containing so little money. 'I am still very puzzled. What was the point? It's really odd.'
