Investigation launched into powder sent to Late Late Show host

The Los Angeles Police Department is currently investigating a white powder scare at CBS Television City after an envelope containing a suspicious substance was mailed to Late Late Show host Craig Ferguson.

The substance, believed to be mailed from somewhere in Europe, was determined to be harmless, but two people were briefly quarantined after coming in contact with it, according to

"The Major Crimes unit is handling the investigation," Officer Karen Rayner of the LAPD, said, E! News reports. "The letter did contain some threats directed at Craig Ferguson. They will be working with the FBI and our counterparts in Europe to investigate the crime."

Craig Ferguson responded to the threats via his Twitter account.

"Ack!Someone mailed my show white powder & claimed it was anthrax," he wrote, according to "I'm not a big fan of that sort of thing."

The Federal Bureau of Investigation, also involved in the Late Late Show case, is concurrently investigating a threat against David Letterman that was made on a website often used by members of Al-Qaeda. A private firm that monitors the website noticed the threat and informed authorities. Letterman’s company, Worldwide Pants, also produces the Late Late Show.

In November, CBS received an envelope containing a white powder at the building where the show Dancing with the Stars is filmed. The package, actually containing talcum powder, reportedly held an implied threat to show contestant Bristol Palin, according to E! News.
