There is the part where his touring partner Josh Denny says "he’s rotting away in jail..."
I guess you don't believe him, but that wording does indicate that McInnes was arrested, because that is how one ends up in jail.
There's no specific evidence of an arrest, but the article does support the plausibility of an arrest. If he's in jail, that livestream incident was probably where he was arrested.
