Yoochun is planning to comply with police investigations without being summoned.
His law firm said, "Yoochun will be turning himself over to the police on the 17th at 10AM to the Gyeonggi District Precint for investigations. He already expressed his intent to do so on the 10th during his press conference because he had not done drugs and wanted his name to be cleared. His date was determined after negotiating the schedule with the police."
Earlier today, the police had received a warrant to search and seize his residence, his cars, and his phone.
