EXCLUSIVEPolice showed up to Ashton Kutcher's house ready to defend the actor from a home intruder ... only to realize it was ANOTHER false alarm ... but this time swatters were not to blame.
Law enforcement sources tell TMZ ... cops rushed to Ashton's L.A. digs around 5:30 AM earlier this week after a friend (who was crashing at his pad) heard a scary noise, thought there was an intruder and pressed the panic alarm on the security system.
We're told cops arrived and searched AK's entire property, but found everything to be kosher -- there were no signs of a break-in or home invaders.
Ashton was not home at the time.
As TMZ previously reported ... it's not the first time cops have made a run to the Kutcher crib. AK was "swatted" last year after a prankster told police there was a gun battle in his house.
