Singer Wheesung is under investigation for alleged propofol abuse.

Rumors arose last year when Amy's propofol controversy broke out, that a male singer, who is carrying out his military service, was also speculated to be involved with the drug as well.

It turns out that male singer is Wheesung, who is thought to have used his breaks during his military service to be administered propofol at various clinics since 2011.

Back in April, police searched two medical centers and they have now also obtained records detailing the days Wheesung had off from the military.

It's said that Wheesung's medical records revealed that he had been illegally administered propofol as well as valium and other drugs during his vacation days.

Wheesung is currently scheduled to be discharged from his military service this coming August.
