Nine original Andy Warhol prints were quietly stolen from a Los Angeles movie business and replaced with fakes in an art heist that went undetected for years, police and court documents showed on Thursday.

The silk-screen prints worth an estimated $350,000 are from the artist's 1983 series "Endangered Species" and his 1980 "Ten Portraits of Jews of the Twentieth Century," according to a police report submitted to Los Angeles Superior Court as part of a search warrant affidavit.

The theft was first reported earlier this week by celebrity website TMZ.
