Kai Ko, the Taiwanese actor who was arrested by police with Jackie Chan’s son Jaycee in China earlier this month, has been released. He was held for 14 days and vowed never to use marijuana again in a press conference after his release.

“I am so sorry. It was all my fault, with no excuse and no reason,” Ko, 23, told the media, reports Xinhua. “It was an individual behavior, selfish and stupid.”

Ko was in tears as he apologized to his fans, saying that he didn’t realize how important he was to them.

“I never realized that Kai Ko is more than just a name for myself. It also means a lot to those who support and love me,” Ko said, reports The Associated Press. “It was out of my expectations that anything concerning 'Kai Ko' could have such a big impact on others.”

Ko and Jaycee Chan were busted back on Aug. 14, as Chinese police continue to crack down on the use of marijuana among the rising urban class.

Jackie Chan later issued a formal apology for his son’s behavior, writing that he was “heartbroken” and vowed to stand with his son.

“I say to Jaycee that you have to accept the consequences when you do something wrong. As your father, I'm going to face the road together with you,” Chan wrote in a blog post.

Jaycee Chan is still being detained and could face a longer penalty, since police suspect him of sharing his drugs with others.
