UPDATE:

According to the Associated Press, the explosion was the result of a malfunctioning piece of construction equipment in the headquarters’ lobby.

From the AP:

Emergency responders were dispatched to the police division Tuesday evening after employees on multiple floors of the building heard an explosion. Police say the boom was traced to a battery in a hydraulic ladder in the lobby that was being used for an insulation project.

No one was injured, and there was no major damage. Bomb squad members and federal investigators were sent to the scene as a precaution.
