Jackie Chan son was arrested in a Beijing drug bust, according to reports. Police announced Monday that a pair of actors — identified in local reports as Jacyee Chan, 31, and Taiwanese movie star Kai Ko, 23 — were among several suspects detained on illegal drug-related offenses four days earlier, the South Chinese Morning Post reported.Though not directly identified except for the family surnames of Chan and Ko, police said both actors tested positive for marijuana and confessed to using the drug. The younger Chan also faces charges for “providing a shelter for others to use drugs” after investigators removed 100 grams of marijuana from his home. If convicted, Chan could face up to three years in prison on the charge, according to the report.Ko, also known as Chen-Tung Ko, who once vowed to never use drugs in a 2012 public service announcement, faces a less serious detention of up to 15 days, the People’s Daily Online reported. Jaycee Chan’s arrest is a major black eye for his famous father, who has spent years campaigning against drugs.The scion of the action star and Taiwanese actress Feng-Jiao Ling had carved out a career of his own in the Hong Kong and mainland Chinese film industries, with critically acclaimed turns in movies such as 2009’s “Mulan: Rise of a Warrior.” The detentions, part of a Chinese crackdown on drug use among high-profile celebrities, come days after 42 entertainment agencies proclaimed a boycott of any actors or singers caught using narcotics.
