Jaycee Chan, the 32-year-old son of kung fu star Jackie Chan, has been detained by police in Beijing, according to media reports.

Chan is one of two actors who have become the latest targets of Beijing's anti-drug campaign, the reports said.

Police said they confiscated more than 100 grams of marijuana at Jaycee Chan's home and the next day arrested another man surnamed Song, who allegedly sold the drugs to the pair.
