The man was accused of assault with a deadly weapon after American comedian Dave Chapel was attacked on stage during a stand-up show.
Chapel fell to the floor just as the show ended at the Hollywood Bowl in Los Angeles.
A 23-year-old man named Isaiah Lee has been charged, Los Angeles police said.
Earlier, police told NBC that the suspect was armed with a copy of a gun that could throw out a knife blade.
“The man was born and engaged” comedian, wrote on Twitter journalist Brianna Sachs.
She said the guards “rushed in and started kicking and kicking Chapel’s attacker.”
Among those who tried to help was actor Jamie Foxx.
Later in the video it can be seen that the attacker was loaded into an ambulance with a dislocated arm.
Another journalist at the exhibition said that they “rushed” to Chapel and sent him to “fly in the air.”
“He fell on his back, raising his arms and legs. Obviously he was shocked. We were all shocked …” Sharon Carpenter said.
In a video on social media immediately after the incident, Chapel joked about the attacker: “He was a trans man.”
Some criticized the comedian for his jokes about the trans community, and it was a a negative reaction last year against his special-purpose Netflix.
The show also featured his stand-up comedian Chris Rock, who received a slap from Will Smith at the Oscars.
“After the attack on Chapelle, he came on stage and they joked that it was Will Smith,” Brianna Sachs tweeted.
Chapel also spoke of the need for more security following his recent dispute, as well as the incident with Chris Rock, according to audience members.
British comedian Jimmy Carr was on a Hollywood show and posted a photo with Chapelle.
“I’m just glad everything is fine,” he tweeted.
The incident happened during the last of Chapel’s four performances at the venue of the Netflix Is A Joke comedy festival in Los Angeles.
The 48-year-old later returned to the stage to thank Jamie Foxx for the intervention.
“Every time you’re in trouble, Jamie Foxx will show up in the sheriff’s hat,” he joked.
“This man is an absolute genius – we have to make sure we always protect him, man – that’s what we’re talking about …” Fox replied.
A Hollywood Bowl spokesman said an “active investigation” was under way.
Last year, Chapelle fell into a culture of abolition after reacting to his special issue of Netflix, in which he said that “gender is a fact” and declared himself part of the “TERF team” – which means a trans-exclusive radical feminist.
However, he also said he was ready to discuss his show with members of the transgender community.
