Mixed responses follow Ko's public apology

Chinese celebrities caught with drugs

Ko was detained by Beijing police in August and released last Friday.

He says he used drug at Jaycee Chan's mansion in Beijing and all the drugs were provided by Jaycee Chan, son of kongfu star Jackie Chan.

The 23-year-old actor reported to the Taipei District Prosecutors Office on Monday.

He was accompanied by his lawyer and gave no response to media questions.

During the court inquiry, Kai Ko was asked to provide hair and urine samples for further examination.

The results will come out in a week.

His lawyer applied to the court for a postponed prosecution, saying Ko will go to rehab in a hospital at his own expense.

The actor came to fame in 2011 after performing in the movie "You are the apple of my eye".

He has held two press conferences to express his regret over his wrongdoings.
