RUSSELL BRAND SWATTED

The swatting epidemic continues ... this time, the victim is Russell Brand, TMZ has learned. 

Law enforcement sources tell us ... cops raced to Brand's L.A. home after receiving a call from someone reporting two men with guns approaching the home. 

We're told the caller told police one of the men was black, one white -- and they were each sporting body armor. 

When cops arrived to the scene, no one was there -- Russell had left the home 30 minutes prior to the call. 

After a thorough inspection of the property, cops eventually determined the whole thing was a prank -- another "swatting" incident ... just like Bieber, Ashton Kutcher, Diddy, the Kardashians, etc.
