Beijing (AFP) - The son of kung fu star Jackie Chan was released from jail in the Chinese capital on Friday after serving a six-month term for drugs offences, his agency said.

According to Chinese web portal NetEase, Jaycee Chan gave journalists the slip by getting into the back seat of a waiting car in the wee hours of Friday morning (Feb 13) at Dongcheng District Detention Centre.

The car was reportedly speeding and running red lights in order to dodge the media, who later attempted to stop the car at a toll booth. It was reported that some journalists suffered minor injuries when the driver sped off.

The younger Chan, who like his father has worked as an actor and singer, was detained in August last year and charged with providing a venue for others to use drugs after police found 100 grams of marijuana at his home in Beijing.

The 32-year-old had already spent five months in prison when he was sentenced in January after pleading guilty to the crime.

Chan and his management M'Stones International will hold a press conference on Saturday at which the star will "formally apologise and explain to the public", said a press statement from the company.

At least 10 locally-known stars were detained on drug-related charges last year, according to state-run media.

Experts say the arrests are part of a wider campaign by Beijing to promote morality. Chinese authorities have also targeted prostitution and the broader illegal drugs trade over the past year.

Jaycee Chan has featured in several films but not yet won the acclaim earned by his father, one of Asia's best-known actors with a string of Hollywood hits to his name.
