Missoula police blocked off downtown streets Monday morning after a suspicious package was found outside the Russell E. Smith Federal Courthouse.

The black package was found in front of the courthouse on North Pattee Street with the words "Save Palestine" and a red smear spray-painted on the wall above it. A purple symbol was also painted on the front door of the building.

The package was roughly the shape of a person, and appeared to be made of cardboard and covered with garbage bags. It was taped to the wall of the courthouse.

During the brief investigation, federal employees were moved to the back of the courthouse while police blocked off sections of East Broadway, East Front Street and Pattee Street. The roads reopened about 9:45 a.m.

Police dogs from the University of Montana and X-rays determined the package was not a bomb.

FBI agents removed the package after taking over the investigation. They refused to comment about the contents of the package or the incident.
