Several streets in downtown Seattle near Third and Seneca were reopened after 5 a.m. Monday after a bomb squad destroyed a suspicious device outside FBI offices.

TV reporters at the scene say federal security agents reported the device and the Seattle police bomb squad used a robot to destroy it with a controlled blast. Investigators picked up the pieces and no one is saying yet what it may have been.

Police said on Twitter the situation is being managed by federal agencies. The FBI said a public information officer was not immediately available to comment.
