TEMPE, Ariz. >> The 21-year-old son of actor Jean-Claude Van Damme is accused of holding his roommate at knifepoint at their apartment in suburban Phoenix.

Tempe police say Nicholas Van Varenberg was arrested Sunday night on suspicion of aggravated assault with a deadly weapon, unlawful imprisonment, marijuana possession and possession of drug paraphernalia.

He’s out of jail after posting a $10,000 bond.

Van Varenberg didn’t have a lawyer at his initial court appearance, and it’s unclear if he has one yet with a Sept. 20 preliminary hearing looming.

Court documents released Tuesday say police went to the apartment after receiving reports about loud noise and yelling.

Police say Van Varenberg became upset at his unidentified roommate for answering the door for police, grabbed a knife and kept his roommate from leaving the apartment.

Van Varenberg is the youngest son of Van Damme, known for his martial arts action films of the 1980s and 1990s.
