Bomb found at philanthropist George Soros’ home

A bomb was found in a mailbox at the suburban New York compound of George Soros, the liberal billionaire philanthropist who has been the target of right-wing conspiracy theorists, authorities said Tuesday.

Federal investigators were reviewing surveillance video to determine whether the package had been sent through the mail or delivered some other way, officials said.

A security officer at the compound about 50 miles north of Manhattan became suspicious of the package Monday afternoon and placed it in a wooded area before alerting the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives, authorities said. Agents came out and safely detonated the device, which a federal law enforcement official said contained explosive powder.

“It was not a hoax device,” said the official.

Another federal official said the device resembled a pipe bomb and was inside a package placed in a mailbox outside the gates of the compound. It was opened in a secure location just inside the gates, nowhere near Soros’ quarters, the official said.

Soros, who made his fortune in hedge funds, frequently donates to liberal causes. Recently, conservative critics have accused him without evidence of secretly financing the caravan of Central American migrants making their way toward the U.S.
