An official from the Gyeonggi Southern Police Agency Drug Investigation revealed in a call to Dispatch on the 18th that "B.I admitted to some of the charges during investigation."
B.I attended investigations at the National Police Agency on the 17th as a reference but because he admitted to some of the drug charges his status has been switched to suspect.
The police official stated, "There was a mismatch in the statements provided by B.I and 'A' [Han Seo Hee] so we're conducting further investigations. We will summon Yang Hyun Suk soon to investigate whether he appeased and threatened A at the time and whether he obstructed police investigations into B.I's case."
In a related development, according to eToday, A [Han Seo Hee] reportedly attended police investigations privately on the 16th before B.I was summoned.
