A Hong Kong student was abducted at gunpoint from her home in Canada by a group of men who burst into her flat and tied up her mother, a Vancouver court heard. Chong Ka-wai, 24, who was also born in Hong Kong, pleaded guilty in a Richmond court on Wednesday to abducting the 18-year-old student and demanding C$500,000 (HK$2.61 million) ransom from her father, who runs a linen store in Vancouver. He admitted charges of unlawful confinement, kidnapping for ransom and administering an overpowering drug. In a brief appearance, Chong listened to an interpreter as the judge set the sentencing date for October 4. The girl, who emigrated to Canada four years ago and cannot be named because of a court-ordered ban, had been held by the kidnappers for 11 days. The family told police their daughter had been abducted after a group of men burst into their home on December 11. They tied up the mother and drove the girl away in her black Nissan 240 SX. Police used up to 60 officers, including the dozen or so who speak Cantonese. Chong has been held in custody at the Vancouver pre-trial centre since his arrest on December 22. Police arrested Chong's alleged accomplice, Chan Chi-wai, 21, on the same day. Investigations showed the two suspects called each other throughout the 11-day kidnapping. Chan still faces 10 charges, including kidnapping, extortion and sexual assault. A preliminary inquiry for Chan is scheduled for November 17. Police believe others were also involved in the kidnapping but have been unable to make any more arrests.
