The authorities in Beijing have approved the formal arrest of the son of the Hong Kong film star Jackie Chan on suspicion of “accommodating drug users,” a step that paves the way for possible charges and a criminal trial.

Jaycee Chan, 31, was detained last month after a raid on his home in Beijing. The police, acting on a tip, reported finding more than 100 grams of marijuana at the residence. The younger Mr. Chan and Ko Chen-tung, an actor from Taiwan, both tested positive for marijuana use, the police said.

On Wednesday afternoon, the procurator’s office in the Dongcheng District of Beijing announced on Sina Weibo that it had approved the detention. That declaration allows the police to continue holding Mr. Chan and investigating his case. It also increases the likelihood that he will face criminal charges.



If convicted of allowing the use of illegal drugs, Mr. Chan could be sentenced to up to three years in prison.

Several celebrities have been caught up in Beijing’s crackdown on vice crimes this year, including at least 11 for drug-related offenses, according to Xinhua, the state news agency. On Monday, the police said that Wang Quan’an, the award-winning director of such films as “Tuya’s Marriage” and “White Deer Plain,” had been detained on suspicion of hiring prostitutes.
