Two cash couriers have admitted they took bribes to assist a cross-border mobile phone smuggling racket using their employer's armoured vehicles. Hui Ping-kee, 51, and Sze Ho-chun, 54, are former employees of Securicor Hong Kong Ltd, which provides cash conveying services from Hong Kong to the mainland. Hui was an armoured car driver and security guard for the company and Sze the crew commander. Each pleaded guilty in the District Court yesterday to one count of conspiracy to offer advantages, with themselves being the beneficiaries of the deal. Hui pleaded guilty to a separate charge of conspiracy to smuggle the phones. Prosecutor Wong Hay-yiu said Hui was deployed to carry cash from Hong Kong to the mainland about three times a week. Sze was responsible for supervising Hui's work. The court heard they were approached by alleged mobile phone smugglers Chau Sau-kit, 40, and Chow Cho-fung, 42, between October 1999 and August 2000 to transport mobile phones and accessories across the border in one of their company's armoured vehicles. Chau and Chow denied two charges each of conspiracy to smuggle the phones and conspiracy to offer an advantage. Their hearing before Judge Peter Line continues today. Hui and Sze were arrested on August 23, 2000, at Man Kam To control point after 950 mobile phones and 928 batteries were found in their vehicle. Hui told ICAC officers that he had been paid between $2,000 and $5,000 for previous deliveries by Chau. Sze admitted he received sums ranging from $500 to $2,000 from Hui each time, the prosecution said. Judge Peter Line adjourned sentencing until Monday.
