On the afternoon of November 4 KST, actor Lee Sun Gyun appeared outside Incheon Nonhyeon Police Station, on his way to attend the second police questioning in his ongoing illegal drug use investigation.

Following his first questioning, which took place on October 28, Lee Sun Gyun appeared in person at the police station once again after approximately one week. 

Before entering the police station, Lee Sun Gyun stopped in front of the press and bowed deeply. He said, "I would like to once again sincerely apologize for causing many people concerns. I will participate diligently in today's investigation. Once again, I apologize."

Previously on November 3 KST, the National Forensic Service reported that Lee Sun Gyun's hair follicle test results returned negative for illegal drugs such as marijuana, detecting no drug use in the last 8~10 months at the time of the hair follicle extraction. 

However, the police are awaiting additional test results from Lee's leg hairs to confirm whether or not the actor used illegal drugs more than 10 months ago. 

Meanwhile, Lee Sun Gyun is known to have paid the owner of an adult entertainment establishment, 'A' approximately 350 million KRW (~ $267,000 USD) after being blackmailed.
