Lee had been questioned three times by police, including for 19 hours over the weekend. The actor had said he was tricked into taking drugs by a bar hostess who then tried to blackmail him, Yonhap reported.

So instead of following up with the claim of him being drugged, they decide to lock him inside a room for a whole day and presumably threatened prison time and/or a damaged reputation, all while suspecting he was on mind altering drugs (which are known to fuck you up when you’re in a hostile headspace). Then he gets released and commits suicide

Seems like they got a smart bunch over there
