Federal and local law enforcement officials were working with Burbank police Saturday to track down the culprit who sent an envelope filled with a mysterious, dangerous-looking white powder to the Burbank cops.

The white powder turned out to be harmless, but that was not determined until after the Burbank police headquarters were locked down for a good portion of Friday afternoon.

Led by Burbank Police detectives, a multi-agency investigation that includes the FBI and the United States Postal Inspector was launched.

The white powder was delivered in an envelope addressed to the police department and opened by a police employee at 2:35 p.m. Friday, Burbank police spokesman Sgt. Claudio Losacco said.

“The administrative offices of the police building were cordoned off and the Burbank Fire Department responded with their hazmat team,” the sergeant said.

“Our partners with the Los Angeles County Sheriff’s Department hazmat team also responded,” he added.

The powder was deemed to be no threat by 5 p.m. Friday, and the building at 200 N. Third St. was cleared for occupancy, Losacco said.
