Man, flipping through his twitter feed... I just hope for the best. He's an incredible dude.
I've read (on reddit, lol, obviously just speculation) the team hotel was involved, police we're probably involved (but there is no official report yet), and that drugs and/or violence were involved. That's internet grain of salt gossip, but that's what i've noticed reading around.
I can't help but speculate myself by reducing it - I wonder if he was physically subdued/restrained/arrested at the team hotel - where while the charges or allegations were petty - he was simply drunk (witness spread "he was on something" - turns into cocaine on reddit) - and then it escalated to a police altercation and a physical arrest in front of the team at the hotel... I could imagine a situation where if EG did not want to be arrested it take a small task force to do it... and if it was something petty enough, perhaps the police wouldn't be excited to talk about it and confirm the pointed speculation that he was arrested at the team hotel?
