Yoo Ah In was absent from his second police investigation and the police revealed that if the actor's absence continues, they will be requesting an official warrant to arrest him.

On May 15 KST, Yoo Ah In, who is currently undergoing investigations on charges of doing five different types of illegal drugs in South Korea, was absent to his second scheduled police investigation. Following his absence, the Police Department's investigation division stated, "It will be best to coordinate a date for his attendance as soon as possible and complete our investigation. If that doesn't work out, then it will have to be done by [arresting him with an official warrant]."

Yoo Ah In was scheduled to undergo a second police investigation on May 11 KST, but he refused to receive investigation and returned home as there were many reporters outside the Mapo building of the Seoul metropolitan police department. The police notified Yoo Ah In of the rescheduled date of his investigation, but Yoo Ah In is currently in a situation where he received a summons from the police. If refusing this summons, then the police revealed they will have to request an official warrant to arrest the actor.
