Glee creator Ryan Murphy's office was reportedly evacuated on Monday after a suspicious powder was discovered in the mail.

Police were called to the production company in Los Angeles after "a little bit of white powder" spilled out of a letter from a fan asking Murphy to read his script, reports Deadline.com.

Staff were ordered to leave the building while a hazardous materials team conducted a brief investigation.

Work resumed after the officers determined the substance was not dangerous, according to a spokesman for the Los Angeles Police Department.
