Police are allegedly unable to proceed with further investigations into Yoochun's counter suit against his accuser due to the defendant party's non-cooperative conduct. 

This past June 20, Yoochun and his label's president, Baek Chang Joo, counter sued red light district worker Lee, her boyfriend, and a man identified as Hwang, who claimed to be Lee's cousin, for slander and blackmail. 

On June 20, police questioned Baek, and they also questioned Baek's father and the father's acquaintances on the following June 21 and 22. However, police are unable conduct any further investigation and questioning for the defendant's party as they are allegedly being uncooperative.

If the defendants continue to resist the authority, then police plan request official arrest warrants.

Hwang in particular has been on the police's radar since three years back for being affiliated with a gang from Ilsan. Baek's father is also reported to have been a part of a gang, and police are investigating whether the gangs intervened at all in the process of the the two parties trying to reach an agreement. 

Currently, both Yoochun and Lee's party are banned from leaving the country. 

After finishing up their round of investigations with the defendants, police expect to summon Yoochun some time in the next week.
