According to the Gangnam Police Station, 'A', who is acquainted with Yoochun, sued the singer for medical costs since being bit by Yoochun's dog while visiting the famlily's house back in 2011.
C-JeS Entertainment said, "Back in 2011 at Yoochun's house, the accuser, who is his past manager's friend, went to his balcony to look at Yoochun's dog, and was attacked. Yoochun went to the friend's hospital with his manager, apologized, and paid for their hospital fees. Last week, the accuser sued Yoochun for 1.2 billion KRW (1.1 million USD), and we found about the suit today. Yoochun has never been contacted for the past 7 years by the accuser about their continuous, 7-year treatment, so he is currently looking over the suit with his family. He will be checking the truth of the situation through the police and will work to resolve the situation amicably."
Reports stated that 'A' has been receiving treatment for their dog bite to their face for the 7 years, and that 'A' ran into issues with his ongoing treatment, despite the length of time passed.
