Authorities say the number of Tennessee courthouses involved in a rash of false bomb threats has risen to 29.
Tennessee Department of Safety and Homeland Security spokeswoman Dalya Qualls said Tuesday that nine threats were reported in West Tennessee counties, including the federal building in Memphis. Qualls says there were six bomb threats in Middle Tennessee and 14 in East Tennessee.
Many buildings had to be evacuated after the threats. Qualls said no bombs were found.
Tennessee is at least the fourth state this month to deal with phony bomb threats at courthouses. In Oregon, 28 courthouses were threatened last week, and similar threats were reported in Nebraska and Washington.
