The man accused of assaulting comedian Dave Chappelle during a performance in Los Angeles earlier this month has been charged with attempted murder in a completely unrelated incident.

According to the Los Angeles County District Attorney’s Office, Isaiah Lee, 23, is accused of stabbing his roommate during a fight at a transitional housing apartment last December.

According to the DA’s office, “as a result of media reports about the Chappelle case,” “the victim recently identified Lee as the person who committed the assault he had previously reported to police.”

“Based on the nature and severity of the December attack,” L.A. District Attorney George Gascón said in a statement.

When Lee appeared in court on Thursday to face the attempted murder charges, he pleaded not guilty.

Lee is accused of rushing Chappelle onstage with a replica during his performance at this month’s Netflix Is a Joke Festival.

He pleaded not guilty to four misdemeanour counts, including battery, assault with a weapon, unauthorised access to the stage area during a performance, and commission of an act that delays or interferes with a performer.
