Entertainer Flavor Flav is jailed in Las Vegas on felony assault and misdemeanor domestic battery charges after police say he argued with his fiancee and threatened to attack her teenage son with a knife.

Officer Bill Cassell says no one was injured in the scuffle about 3:30 a.m. Wednesday at a home in a residential neighborhood several miles southwest of the Las Vegas Strip.

The 53-year-old former rapper and reality television star’s legal name is William Jonathan Drayton Jr.

He’s being held on $23,000 bail at the Clark County jail, with an initial court appearance scheduled Thursday. It’s not clear if he has a lawyer.

Drayton was part of the 1980s and 90s rap group Public Enemy. His public persona includes wearing a big clock on his chest.
