Damn it, William! Flavor Flav has been arrested in Las Vegas, following an alleged assault with a knife. Apparently, he’d gotten into an argument with an unidentified teen in his house (police are not sure if that’s his child), as well as his fianceé. She then called 911, saying he’d threatened one person with a knife during the argument, and battered the other and it’s not clear at the moment which is which. He was promptly arrested when police arrived on scene around 3am, and booked on felony assault with a deadly weapon and misdemeanor domestic violence (battery). He’s currently being held on $23k bail. His crazy mugshot, along with some other photos, in the gallery.
