We were there on Saturday night as well and went up to the bar. Chris Brown (we assume) had rented out the Roof Terrace for a party until 8:30 pm. Lots of people and loud music up there, obviously. When we left for dinner, we saw his bus outside the hotel. We had no idea who it was or what was going on until I saw Chris Brown had been arrested outside the hotel and the article had a picture of his tour bus.
