The thing around Suga is still ongoing, because the investigation is still ongoing. But there was a whole thing and false infos (with some korean media) and hatersβ hashtag going around.
A media was showing cctv footage saying it was Suga, and that he was going faster than the limits and other thing. But these cctv footage, were later revealed not being Suga, with the actual footage, showing him going at the speed of someone walking, but falling and the police going to him. The medias that showed those false cctv, later apologized.
His alcohol level and other infos are not yet revealed, I think, but like I said the police is still investigating and he need to go for questioning (something which the korean media are patiently waiting for). In short from what was shown there was no real accident, except him falling.
And I might be biased when I say that, but all this drama is only because he is someone from BTS, and the media are searching for a drama to amplify. Because I think later a baseball player did have an accident while being intoxicated but it did not have the same extent.
In short it is still ongoing, and there was/is a lot of thing going on, and no real verdict on his level and the sentence, it might be something big or nothing.
