> Rukstales was arrested for unlawful entry.

That may have been just what they needed to detain him. I suspect they can add other more severe charges once they have more evidence?

Absolutely. The arrest on trespassing and other low-level charges establishes his presence in the building at the time of the event and as an active participant. Next step are sedition charges.

He’s not being detained. He was charged and released the same day.

He has to show up to a court date and then a jail date.

Different person. The CEO has not been arrested (yet).
