A company controlled by a recently abducted Hong Kong deputy to the Chinese People's Political Consultative Conference is being sued by a transport firm. Tsinlien Transportation Company is suing Flow-Chart Investment for $1.5 million in unpaid loans, said a High Court writ filed yesterday. Deputy to the CPPCC Liu Chi-keung is Flow-Chart's main shareholder. Tsinlien claims to have lent Flow-Chart $1,559,748 since July 1995. The debt was not repaid by the deadline of October 12 last year, the writ said. No money had been forthcoming despite repeated demands, it said. Mr Liu, 64, was abducted in November during a trip to Shanghai. He was released three weeks later. A business dispute involving a state-owned Tianjin investment company reportedly lay behind the abduction.
