2PM’s Nichkhun has written an official apology letter on Twitter.

The embattled singer tweeted through his personal Twitter on July 26 in English saying, “I would like to write this letter of apology for such an irresponsible act. To the injured person, his family, the people of Korea, my fans, JYPE family and staffs, 2PM members, and all the people this situation has affected. I have betrayed the ones who have given me their love and support, the love and support I don′t deserve with such behavior. I feel the need to take some time off to re-think about my action and myself, to make myself a better person and never again repeat the same mistake. I am truly ashamed that I have disappointed so many, and I am deeply sorry.”

Nichkhun was involved in a car accident in the early hours of July 24 with a motorcyclist in Seoul. At the time, Nichkhun’s blood alcohol content was revealed to be 0.056 percent, leading to a suspension of his license.

Additional comments from JYP Entertainment in response to Nichkhun′s Tweet have not yet been issued.
