Jaycee Chan, the 31-year-old son of Kung Fu star Jackie Chan, has been arrested in Beijing on drug-related charges, the South China Morning Post, or SCMP reported Monday, citing local media. Beijing police also detained 23-year-old Taiwanese movie star Ko Chen-tung, better known as Kai Ko, along with Jaycee, SCMP reported, citing Beijing News and Beijing Times.

While it was unclear when the two were arrested, local media reports said that they were involved in illegal drug use. Ko’s agency reportedly could not reach out to him after news of his arrest surfaced online.

"We have sent people to Beijing to find out more information, and we will issue an official statement by 8 p.m. to tell the public what we have found," the actor's agency said, according to Focus Taiwan, a local news channel. "Please allow us some time to get a better understanding of the situation. Thank you for your patience and tolerance."

According to reports, Ko, who won Best New Actor at the 48th Golden Horse Awards and the 12th Chinese Film Media Awards for his starring role in the film “You Are the Apple of My Eye,” has been inactive on his Weibo social media accounts since last Tuesday. The news of the two stars being involved in the consumption of illegal substances reportedly went viral on Chinese social media.

According to SCMP, which cited Beijing News, the two actors could face potential criminal charges.
