A box filled with manure and addressed to Steven Mnuchin, the treasury secretary, was left Saturday at his neighbour’s home in the upscale Bel-Air neighbourhood of Los Angeles, police told KNBC-TV.

Helicopter footage from the station showed the manure spilling onto the ground after authorities emptied the box, which was covered in Christmas wrapping paper.

A Christmas card that referred to Mnuchin and U.S. President Donald Trump was inside the package, which was labelled as coming from “the American people,” KABC-TV reported.

The Los Angeles Police Department told the television station KTLA the package contained horse manure. The box raised suspicions and the bomb squad was called to investigate.

A Police Department spokesman did not immediately respond to a request for comment Sunday.

Mnuchin, who was home at the time, “was made aware of the situation” but was not in immediate danger, Rob Weise, a watch commander with the Police Department, told KNBC.

A Secret Service spokesman told The Associated Press that the agency was aware of the episode but declined to comment further.

Mnuchin, a former hedge fund manager and Hollywood film financier, was confirmed in February as treasury secretary and helped plan and pitch Trump’s tax plan. During his time in office, he has come under fire for flying at taxpayer expense on military aircraft for trips that cost more than $800,000.

The Treasury Department’s Inspector General reviewed the air travel after Mnuchin’s wife, Louise Linton, posted a photo on Instagram in August of the couple leaving a government airplane and highlighting the high-end luxury brands she was wearing.
