The son of Hong Kong film star Jackie Chan, who has been detained on drug-related charges, was shown on Chinese television with boxes of cannabis as state-run media revealed details of the case Tuesday. Beijing police last week detained Jaycee Chan, who like his father works as an actor, ‘on suspicion of accommodating suspected drug users’, China’s official Xinhua news agency reported. Police seized more than 100 grams of cannabis from Chan’s house, in a swoop which also saw a Taiwanese actor known as Kai Ko detained on drug charges. China launches periodic crackdowns on illegal drug use, which in the past have involved arresting celebrities. At least 10 locally-known stars have been detained on drug-related charges this year, state-run media have said. Chan, 31, was shown on state TV late Monday with his face blanked out as a plain-clothed investigator pulled small boxes of drugs from a cabinet in his Beijing home.
