Kiether Sutherland- In trouble again?

Tv guide is reporting the Kiether Sutherland is under investigation for head-butting a fashion designer in an argument concerning Brooke Shields. "The 24 star tried to be a hero after the designer, Jack McCollough, knocked into Shields at a bar, New York's Daily News reported Wednesday." He wanted the designer to apologize to Brooke shields but according to the reports the designer says he did not do anything wrong. "The designer was not believed to have suffered a broken nose or to have required hospitalization, a police source told TVGuide.com." They dont know if the investigation will affect 24 production for season 8. What are your thoughts? I think the whole story hasnt came out yet or Kiether just likes getting in trouble.
