Actor Lee Sun-kyun on Saturday appeared at Nonhyeon Police Station in Incheon again, just one week after taking a drug test.

The actor who starred in many award winning films including "Parasite" is suspected of using marijuana and psychotropic drugs. 

Police sent Lee's hair samples to the National Forensic Service for a more detailed examination and the results came back negative.  

However, police maintain Lee may have used drugs a long time ago based on his statement that he paid 350 million Korean won, or more than 260-thousand dollars to a bar hostess after being blackmailed by her.

The actor is accused of using marijuana and other drugs at the hostess's home in Seoul from the start of this year.
