Ashton Kutcher Home Invasion Call Possible Prank

Exclusive Details
1003_ashton_kutcher_article_tmzPolice rushed to Ashton Kutcher's L.A. home today, after someone claimed there was a home invasion robbery with shots fired.

The alleged victim claimed she locked herself in the bathroom and several Russian men with weapons were in the house, robbing it.

The LAPD swarmed the area from land and by air and called out the 3 men who were on the property.  The men have been detained and are being questioned, but one law enforcement source tells TMZ ... they may be workers on the property so the whole thing could be a misunderstanding.

Cops also have not found the girl who was supposedly locked in the bathroom so cops are not sure if there ever was a "victim" in the house.  Translation, it could be a "swatting" prank.

Ashton was not home at the time.
