Priscilla Presley's Bodyguard Takes Down Autograph Seeker

Priscilla was leaving Pantages Theater Wed night in Hollywood when she stopped to sign autographs for a large group of fans -- but one autograph seeker started arguing with Priscilla's bodyguards ... over the positioning of his photo. Seriously.

The guy actually threatened the bodyguards, saying ... "You damage my property, I'm gonna damage something of yours." A few seconds later the autograph seeker learned the true meaning of damage ... as fists start flying!

The bodyguard makes quick work of the dude -- who was already wearing a leg brace -- taking him down to the ground ... and staying on top of him while the autograph seeker threatens to sue.
