Jackie Chan's son, Jaycee Chan, and Taiwanese actor Kai Ko have both been detained by Beijing police for drug-related offences, several Chinese websites confirmed Monday night, Aug. 11.

The Beijing public security bureau said in a statement released Monday evening that police officers detained a number suspects for drug use Thursday, Aug. 14, in Dongcheng District, and these include 32-year-old Hong Kong actor surnamed Chan and a 23-year-old Taiwanese actor surnamed Ko, South China Morning Post reported.

Chan and Ko's urine tests have returned positive results for marijuana, and both actors have admitted to using the substance, according to the police statement. Authorities added that they also recovered more than 100 grams of marijuana from Chan's home.

Chan has been put under criminal detention for the suspected crime of "providing a shelter for others to abuse drugs," and if convicted, Chan could face a maximum prison term of three years.

Ko, on the other hand, would only receive much less severe penalty of "administrative detention," which only carries a jail time of up to 15 days.  

Chan followed his father's footsteps and entered the entertainment industry.  However, his career has not been promising following a string of domestic box office failures and a reportedly fraught relationship with his dad.

Jackie Chan previously revealed that he had written his son out of his will, saying that he preferred leaving his wealth to charitable campaigns across the world instead, The Sydney Morning Herald reported. 

"If he is capable, he can make his own money," he told Singapore's Channel NewsAsia, according to SMH. "If he is not, then he will just be wasting my money."

The 60-year-old "Police Story" actor, who was appointed as an official anti-drug ambassador by the Chinese government in 2009, also previously promised to report his son to police himself if he ever went off course.

Meanwhile, Jackie Chan recently confirmed that he was in early negotiations to star in the fourth installments of "Rush Hour" and "The Expendables" franchises, Variety reported.
