Beijing , China ( CNN ) The son of kung fu movie star Jackie Chan has been released after being jailed for six months in China for drug offenses . Jaycee Chan was detained in August last year after he tested positive for marijuana and police found more than 100 grams of the drug in his Beijing apartment . His management company , Mstones , said he was released early Friday morning and will hold a press conference on Saturday . `` He will make a formal public apology and give a full explanation , '' the online statement said . A Beijing court sentenced him in January but took into account the time he already spent in jail since last summer . Chan pleaded guilty to `` hosting others to take drugs , '' was also fined 2,000 yuan ( $ 320 ) , announced the Dongcheng District People 's Court . The Hong Kong native was arrested along with a Taiwanese actor , amid a government crackdown on celebrity drug offenders . Although he did not attend the trial , Jackie Chan -- who has starred in Hollywood blockbusters like `` Rush Hour '' and was named an anti-drugs ambassador in China in 2009 -- had expressed anger and disappointment in his son in media interviews . `` I failed to discipline him -- now the state is helping me discipline him and make him get rid all the bad habits , '' the elder Chan , 60 , told the state-run Xinhua news agency last December , while denying his son had received special treatment in jail . The younger Chan 's case has put a spotlight on the Chinese capital 's intensifying anti-drugs campaign . By mid-November , the authorities had detained almost 10,000 people for using drugs , nearly double the previous year 's figure . Announcing the numbers , a top anti-narcotics official in Beijing emphasized the government 's `` zero-tolerance '' stance on celebrity offenders due to the impact of their behavior on the youth . Last August , dozens of management agencies representing actors and singers signed an agreement with Beijing authorities , banning drug use from the entertainment industry and pledging to fire any artists who break the law .
