Cops Raid Girls Gone Wild Photo Shoot

According to law enforcement sources ... police went to the home to conduct a "film permit investigation" because there's been an ongoing issue of people -- not only GGW -- shooting there without proper permits.

A GGW rep says they have about a dozen staffers -- including requisite girls in bikinis -- at the home shooting their "Search for the Hottest Girl in America."

The rep claims LAPD entered the private residence without a proper warrant or probable cause.
