BEIJING, Dec. 22 (UPI) -- Jaycee Chan, the son of Kung Fu star Jackie Chan, was charged with drug offense by Chinese authorities Monday four months after he was arrested for possession and tested positive for cannabis.
Chan who also goes by the name Fang Zuming, was arrested in August along with his friend, Taiwanese actor Kai Ko Chen-tung after authorities found more than 100 grams of marijuana at his home.
Chen-tun was released after a 14-day administrative detention but Chan remains under custody.
Jackie Chan, who was a goodwill ambassador for the China Anti-Drug Committee in 2009, addressed his son's arrest days after the fact and stated he was "very ashamed" of his actions.
Chan's arrest came about two years after the Chinese government announced its zero-tolerance policy against illegal substances. His trial yet had not yet been revealed.
