EXCLUSIVEMischa Barton came face-to-face with several police officers on Thursday ... when a fleet of squad cars rushed to her L.A. home in response to a report of a screaming woman on the actress' property, TMZ has learned.
Law enforcement sources tell us, the 911 call reporting the screamer listed Mischa's address as the location of the disturbance ... so multiple cop cars raced to the scene.
We're told cops knocked on Mischa's door and the actress answered -- but there was no screaming woman to be seen (or heard).
According to sources, police determined they were given the wrong address ... and later found the woman in question further down the block.
We're told Mischa's dad was also home when cops showed up -- and he was PISSED, believing Mischa was the victim of some kind of "swatting" prank.
