russellkrav.jpgX17online has learned exclusively that Russell Brand used karate-style moves while attacking photographers at LAX. Sources on scene tell us that at least five photographers were pushed by the actor during the incident.

We're told that Brand complained to cops that the paparazzi were trying to get upskirt shots of his fiance Katy Perry ... who was with him at the time of the beatdown.

A photog on the scene tells us, "This is completely not true. We were doing regular walking shots as Katy and Russell walked into the airport. I can't believe he'd lie to the cops like that."

As for Russell's karate-style attack, he must have been using the Krav Maga lessons he began back in May to get in tip top shape for his upcoming wedding. FYI ... Krav Maga is hand-to-hand combat techniques developed in Israel that involves wrestling, grappling and striking techniques. Here are some photos of Mr. Brand practicing his moves this past June!

Although several photographers were attacked, only one suffered bruising around his eyes. X17online has learned that the photographer will be pressing charges.

Just a few days back, X17online videographers caught Katy Perry exploding on photographers after leaving Boa steakhouse in West Hollywood. These two aren't messing around!
