The elite enclave of Malibu, California appears to have been the target of a ring-wing prank.

Official-looking signs were set up at the city limits on Tuesday, boasting about the town's new status as an 'OFFICIAL SANCTUARY CITY'. But drivers who looked closer saw that not all was as it seemed.

Both signs had taglines criticizing the picture-perfect veneer of the wealth Los Angeles suburb.

'Cheap nannies and gardeners make Malibu great! (Boyle Heights not so much)' one sign read, referring to a predominately Latino neighborhood in LA. The other stated: 'Because our beach community needs cheap labor, dude.'

City council members said that the signs were a prank, and they were taken down by Wednesday morning.

No one has taken credit for the signs so far.

But street artist Sabo said that they were put up by some friends who work in Hollywood and didn't want to be blacklisted from the liberal industry.

'Some friends of mine put those up last night,' the artist told the Hollywood Reporter. 'They aren't big on getting attention seeing they work in the Hollywood industry and as well all know there is a serious Black List in full effect focused on those of us who aren't on the Left politically speaking.'

The signs appeared to be a criticism of Malibu's decision last month to become a sanctuary city.

There are currently about 40 such cities in America, that have promised not to work with Customs and Border Patrol agents in deporting illegal immigrants - at the risk of losing federal funding.

The move was largely symbolic for Malibu, which doesn't even have its own police force to work with federal agents. Critics also pointed out that Malibu is such an expensive place to live that there's like not many illegal immigrants there to protect.

City Council members estimated that about 80 children are undocumented in the town.

Actor Martin Sheen, a resident and first-generation American, pushed for the town to become a sanctuary city.

Leonardo DiCaprio, Jack Nicholson, and Ellen DeGeneres are other famous residents.
