(TMZ) Cops raced to Miley Cyrus' L.A. house Wednesday night after receiving a report about a possible home invasion ... but when they arrived to the scene, it turned out to be a false alarm ... and all signs point to a troubling prank known as "Swatting."
Law enforcement sources confirm ... the LAPD received a 911 call at 6:50 PM to report a possible home invasion, possible shots fired.
The LAPD responded immediately ... guns drawn ... but the house was quiet, no one was home ... and there was no sign of a crime. Cops determined it was a false alarm.
Law enforcement tells TMZ ... officials now believe the caller is a "911 abuser."
The call seems to fall in line with a prank called "Swatting" -- in which a caller tries to trick emergency responders into dispatching law enforcement into a home by making up a crime.
Cops tell TMZ ... if the call was indeed a prank, which it appears to be, the caller will be arrested ... and face serious criminal charges. In fact, we're told if someone were to be hurt or killed due to the prank, the caller could even face felony charges. more on this story
