A SENIOR employee of Mattel, the world's biggest toy company and the manufacturer of Barbie, appeared in court yesterday charged with accepting almost $500,000 in bribes. Leung Kin-wai, 33, accepted a total of $491,192 between May 1994 and Februarythis year, the District Court heard yester-day. Leung pleaded not guilty yesterday to two charges of soliciting an advantage and five counts of accepting an advantage. Prosecutor Edward Laskey said Leung had started work with American-based Mattel Toys Vendor Operations Limited in 1985. It was alleged Leung, a senior manager, solicited bribes from two of Mattel's Taiwanese fabric suppliers, Tex-Ray and Chu Tung Yi, to place Mattel's textile orders with the firms. The court heard Leung unexpectedly quit on February 14, saying he wanted to emigrate to Canada. Six days later, Mattel director Dan Kennedy made a complaint in relation to the bribery allegations. Leung was detained by the immigration authorities at Kai Tak on March 3. The trial continues before Judge Sweeney today.
