China has indicted Jaycee Chan, the actor son of Hong Kong action star Jackie Chan, on drug charges Monday. He could face up to three years in prison if convicted of sheltering others to use drugs. Chan and Taiwanese movie star Ko Kai were arrested in Chan’s Beijing apartment in August. Police said both tested positive for marijuana, and 100 grams of the drug was confiscated. While Ko was released after 14 days, Chan has been detained ever since. The arrest was part of the Chinese government’s larger summer crackdown on young celebrities who used drugs or solicited prostitutes. Jackie Chan was actually named an anti-drug ambassador by the government in 2009. “As a public figure, I’m very ashamed. As a father, I’m heartbroken,” he wrote following his son’s arrest.
