BEIJING, Feb. 13 -- Jaycee Chan, son of Chinese kung fu star Jackie Chan, was released after serving six months in prison on Friday.
On Aug. 14, 2014, Beijing police arrested Jaycee and Taiwan movie star Ko Chen-tung, both tested positive for marijuana and admitted to having used the drug. Police discovered 117.7 grams of marijuana in a bedroom at Jaycee's house.
Ko was released after 14 days detention. Jaycee was sentenced to six months in prison and fined 2,000 yuan (326 U.S. dollars) for drug offenses by the Dongcheng District People's Court in Beijing on Jan. 9.
China has detained a string of celebrities on drug-related and prostitution charges. On Thursday, popular Chinese singer Yin Xiangjie was prosecuted in Beijing for possession of drugs.
Beijing police arrested 45-year-old Yin in a residential community in Chaoyang District in December and seized 13.93 grams of crystal methamphetamine and 1.02 grams of marijuana.
The Beijing Trade Association for Performances said in September it would not hire any stars involved in drug abuse or prostitution. Sixteen Chinese production companies also pledged not to hire stars involved in prostitution, drugs or gambling.
