LOS ANGELES, Dec. 23 (Xinhua) -- A suspicious package addressed to U.S. Treasury Secretary Steven Mnuchin on Saturday night was determined by a bomb squad of Los Angeles Police Department (LAPD) not to be an explosive but manure.

The LAPD said that the package, labeled to Mnuchin and left in a driveway, was reported by someone in the neighborhood, investigators then found it was filled with manure.

Earlier aerial footage from helicopter posted online showed that officers investigating a large box wrapped in paper near Mnuchin's home in Bel Air, a neighborhood 5 km west of Los Angeles downtown in the western U.S. state of California and known for mansions belonging to celebrities and entertainment industry elites.

According to local ABC 7 news channel, the package was also labeled as being from "the American people."

The 55-year-old American banker has been a vocal supporter of the controversial tax reform and is an advocate for reducing corporate tax rates, which was legalized after a 1.5-trillion-dollar tax cut bill was signed by Trump into law on Friday.?
