The California man accused of attacking Dave Chappelle onstage at the Hollywood Bowl in Los Angeles has pleaded not guilty to four misdemeanor charges.

CNN reports Isaiah Lee, 23, on Friday entered a not guilty plea in his first court appearance. He remains in jail on $30,000 bail, and has been ordered him to stay 100 yards away from Chappelle if released. 

Lee is accused of battery, possession of a weapon with intent to assault, unauthorized access to the stage area during a performance and commission of an act that delays the event or interferes with the performer.

If convicted, he could face up to 18 months in county jail and/or up to $4,000 in fines, according to the City Attorney’s Office.

“He charged a person on the stage … in front of hundreds if not thousands … and then tackled the victim and fled from security. When they detained him, he reached for and used the folding knife,” prosecutor Henrico Bautista told the court.

According to the LAPD, Lee was carrying what’s been described as a “replica handgun with a knife blade inside.” He was booked into the Hollywood Division jail early Wednesday after being treated for an undisclosed injury.

Footage taken after the attack showed the suspect Lee on a stretcher and being put into an ambulance. As such, Lee’s public defender, Chelsea Padilla, maintained that her client was the real victim of this week’s incident.

“The only injury was actually to Mr. Lee … facial injuries from 12 people stomping on Mr. Lee while he was on stage,” Padilla said.

Lee is due back in court May 20.
