‘It’s my fault’: Jackie Chan tells of his shame at the drug arrest of son Jaycee

A "furious and shocked" Jackie Chan said he blamed himself after his son was caught in one of the mainland's highest-profile drug busts in years.

Writing on his Weibo microblog, the Hong Kong action film star admitted he had not been a good enough parent to Jaycee Chan, 32, adding: "I'm very furious and very much in shock".

The message, to his more than 22 million followers on China's answer to Twitter, was the first comment by Chan since the drugs raid that snared 32-year-old Jaycee - better known as Jaycee Fong Cho-ming - along with Taiwanese acting heartthrob Ko Chen-tung.

"As a public figure, I'm ashamed," said Jackie Chan, who in 2009 was appointed as Beijing's anti-drug ambassador.

"As a father, I'm in pain. His mother is heartbroken. [I] hope youngsters will take Cho-ming's lesson seriously and stay away from drugs."

Jaycee Chan and actor Ko, 23, were detained on August 14 when they were caught smoking marijuana at a foot massage parlour in Beijing.
