More than 1,000 guns seized in Los Angeles raid

More than 1,000 handguns and rifles have been seized in a raid on a mansion in an upscale neighbourhood in the US city of Los Angeles, law enforcement authorities said.

The weapons seizure came from an anonymous tip that firearms were being sold illegally out of the home, the Bureau of Alcohol, Tobacco and Firearms (ATF) said.

The house, which is mostly hidden from the street by high hedges, is located in the exclusive Holmby Hills area of Los Angeles, near the famed Playboy Mansion and the home of Jay-Z and Beyonce.

Video footage taken by local television stations showed Los Angeles Police Department (LAPD) officers and ATF agents inspecting enormous piles of handguns and rifles on grey tarpaulins outside the home.

"Pursuant to an anonymous tip, ATF and LAPD became aware of an individual conducting illegal firearms (transactions) outside the scope of the federal firearm license that the individual possesses," the ATF said in a statement.

"A large amount of firearms manufacturing equipment and tools have been recovered," the ATF said.

"While the search warrant continues, there has been more than 1,000 firearms seized," it said. "ATF and LAPD have no reason to believe the public is in any danger."
