On August 12, actor Shin Hyun Joon's legal representative released a formal statement, announcing the conclusion of the star's illegal propofol usage investigation. 

Back in July, a former manager 'Kim' who worked under Shin Hyun Joon accused the actor of dodging police investigation after purchasing and using the illegal medical drug propofol. 'Kim' took his accusations further by submitting an investigation request with the Gangnam police, and the issue was reported by numerous media outlets. 

However, as fo August 12, the Gangnam police have concluded this investigation as they have found no evidence to indicate Shin Hyun Joon's involvement in illegal propofol use, ultimately turning 'Kim's investigation request down. 

Currently, Shin Hyun Joon and his former manager 'Kim' are also involved in a two-way lawsuit over the actor's alleged mistreatment of 'Kim' during his employment, defamation of character, etc.
