The Los Angeles Police Department and ABC confirm with EW that police and FBI authorities rushed to CBS Television City Friday after an envelope containing an unknown substance was delivered to the Dancing With the Stars production office. The scare, however, was short-lived: Police cleared the scene after discovering the substance in question was not a hazardous material, but talcum powder. A statement from ABC reads, “Security and the Los Angeles Fire Department and Los Angeles Police Department were immediately notified. Measures were taken to secure the area and ensure the safety of personnel.” The network and LAPD are not revealing any other details at this time.
