Tucson police are investigating multiple bomb threats downtown that have led to building evacuations Tuesday.
Sgt. Pete Dugan said police are investigating threats at the Pima County Attorney Office, 32 N. Stone, 300 W. Congress, 839 W. Congress and 1390 W. Speedway. Occupants of both buildings elected to evacuate.
The threats came in by phone.
Bomb squads investigated all scenes. All except for the Speedway site have been cleared as of 2 p.m. Tuesday.
In a possibly related incident, the Arizona attorney general's office has also been evacuated due to a bomb threat.
