Tennessee authorities trying to dispose of large box with dynamite that prompted evacuations

Tennessee authorities on Friday were investigating a box containing large amounts of dynamite at a metal recycling business that prompted evacuations of people living near the site. 

An explosive ordnance robot was deployed to get a sample of the explosives found inside a box Thursday at CMC Recycling, the Knoxville Police Department said. 

The sample tested positive for ammonium nitrate, which is consistent with dynamite. Bomb squad technicians were working to remove the explosives from the box for disposal.
