The audience member who got booted from Theo Von‘s Anaheim show Saturday night appears to have hit another fan on her way out of the arena … new video obtained by TMZ shows.

The clip shows security talking to the woman we previously showed you being removed from the event … and, she’s clearly having an animated chat with them.

Theo pipes up and asks her to speak to security in the lobby outside the arena … but, she starts yelling at him — and, he’s totally confused why.

A woman — who Theo says is his assistant — then comes rushing up to the group … and, he asks her to figure out why the disruptive woman is so upset. All of sudden, the woman terms and smacks a person in the crowd.

The rest of the clip captures the video we shared with you earlier … the woman walks up the stairs to the sound of boos and pumps her arms in the air in a celebratory manner, clearly unaffected by everyone else’s opinion.

We gotta say … Theo handled this situation really well — dealing with this woman respectfully and keeping the show moving.
