A CONMAN who lured a burglary-alarm company boss into a poker game in Shenzhen and forced him to hand over $34,000 was yesterday jailed for 151/2 months yesterday. Judge Chua in the District Court sentenced Ng Wing-ming, 37, on three counts of theft, one of blackmail and one of common assault. Ng denied all charges, and yesterday paid back all the stolen money. The court heard that a man named Fan telephoned Mr Yiu on May 31 last year and asked him to go to Shenzhen to fix a burglar alarm at a factory. Mr Yiu went and was met by Fan and taken to a hotel to see four other men, including Ng. The men persuaded the company proprietor to hand over his Hong Kong re-entry permit for registration at the hotel. A gang member said the road to the factory was closed because an important person was visiting the area, and another suggested a poker game to pass the time, the court was told. Mr Yiu joined the second round of the game and claimed to have bet only $320. However, he was asked to sign an IOU for $58,000. Fan had threatened to keep his re-entry permit until he signed. Mr Yiu was escorted back to Hong Kong and taken to a Sheung Shui bank branch to withdraw $5,000, which he gave to Ng. He was also made to transfer $29,000 into Ng's account. At the same time, he was punched and threats were made against his family. Prosecutor was Judy Cheung, and Ng was represented by Christopher Lam.
