LAPD officers, the bomb squad and the Secret Service poured into the area.

A neighbor, Prince Frederick von Anhalt, said he and others who live above the home were trapped for about two hours, until police found out it was filled with manure and cleared the scene.

"This is Bel Air. You have $50 million houses and all of a sudden we can't move? We can't go out?" he said. "That's bad. They have to find another way."

The LAPD said the Secret Service took over the investigation.
