Yoo Ah In updated his Instagram with a full apology to his fans. 

"This is Yoo Ah In. 

After the police investigation yesterday I wasn't able to give a sufficient apology. I've disappointed with my actions those who've cared for and loved me and I want to apologize once again. 

I'm sorry. 

Moreover, to those of you who have worked on movies, plays, advertisements, and other valuable work because of me, I wanted to offer my apologies that I couldn't express yesterday. I deeply reflect on those moments when I shouldered heavy responsibilities irresponsibly, and I am deeply sorry for the harm caused to countless colleagues and others who want to realize their precious dreams and goals. I will try my best to shoulder my responsibilities.

Many people supported me and gave me endless encouragement and love and I feel greatly embarrassed and ashamed that I continued to harm myself as I continued on as an actor.  And because of this, I've hurt many people. I'm sorry

During the outbreak of the incident and with insufficient reflection, I clearly realized that my mistake could not be concealed with any excuse. The self-rationalization I brought was wrong, and ultimately can never cover up my stupid choice.

I will honestly participate in future investigations and accept all your accusations and legal trials.

Once again, I deeply apologize.

I'm sorry"
