Jackie Chan's son was arrested in a drugs bust.

Jaycee Chan, 32, and his actor friend Kai Ko, 23, were detained by police last Thursday (14.08.14) after more than 3.5oz of marijuana was discovered at Jaycee's home, according to a statement on Beijing police's official micro blog.

Jaycee's arrest comes as Beijing police are cracking down on drug use but Beijing Municipal Anti-Drug Office deputy director Jin Zhihai insists officials are not targeting celebrities as such.

He told the Beijing Times: ''If there is an increased crackdown on drugs, the number of celebrity offenders will also rise.''

Despite his comments, actor Gao Hu, 40, was arrested for possession of methamphetamine and cannabis just last week.

Like his father, Jaycee is also an actor but his movies have not been as successful as the likes of some his dad's motion pictures including 'Rush Hour'.

Jackie has previously said he wished Jaycee had joined the army when he was younger to ''temper his character'' and revealed he wouldn't be leaving his son any of his millions made from his movie career when he passes away.

Speaking in 2011, he said: ''If he is capable, he can make his own money. If he is not, then he will just be wasting my money.''
