Suspicious Letter with White Powder Sent to ‘Dancing With the Stars,’ Was it Anthrax?

A suspicious letter was sent to CBS addressed to Dancing With the Stars containing white powder, which Los Angeles police have determined was not anthrax.

Los Angeles police apprehended the letter around 2 p.m. on Wednesday in a mailroom at CBS Television City studios. A hazardous materials team tested the white substance and determined was not harmful, nor was it anthrax, according to CBS.

No one was harmed when the suspicious letter was found, CBS reported. Police authorities say it was addressed to Dancing With the Stars and not one cast member specifically. No statement has been made on where the letter was sent from or why.

Outside of mail room operations being suspended for a few hours, no business operations or show productions were affected, CBS spokesman Chris Ender told CBS News, declining to comment on any safety precautions for the future.

Dancing With the Stars has received similar suspicious letters in the past. In November 2010, a letter containing a harmless white powder was sent to CBS studios, prompting a similar investigation days before the finale. Jennifer Grey, Kyle Massey and Bristol Palin were the final three cast members that season.
