Rapper Flavor Flav was arrested in Las Vegas on Wednesday following an argument at his home.

The hip-hop star's fiancée Liz Trujillo called police to the home they share in the early hours of the morning after she and a teenager reportedly got into an altercation with the reality TV regular.

The Public Enemy star was subsequently taken into custody after allegedly threatening one person with a knife and beating the other.

He was charged with one count of felony assault with a deadly weapon and one count of misdemeanor domestic violence.

The rapper, real name William Drayton, Jr., is currently being held on $23,000 bond, according to TMZ.com.
