According to the Las Vegas Review Journal UFC superstar Alistair Overeem has been charged with misdemeanor battery stemming from an altercation at Wynn Las Vegas over New Year's weekend. That would have been the period of time when Overeem was in town for his fight with Brock Lesnar at UFC 141. Overeem won that fight by first round TKO.
It appears that Overeem shoved a woman in the face and, while not arrested, was given a citation. He is scheduled to appear in court on February 21 and faces up to six months in a detention center and a $1,000 fine.
The UFC has not yet commented on the situation and I don't expect them to until after the court date passes and we see exactly what comes out of it.
I seriously doubt he gets 6 months and I don't have the knowledge to really understand how Overeem's nationality affects things.
I will say that, while I'm sure there's more to the story, I'd like to think that there is a way for a 6'5" 260+ pound professional fighter to handle a situation involving a woman that doesn't involve shoving or hitting. So, hopefully this turns out to be nothing.
