Oklahoma City police say a suspicious box found at a utility company's substation that caused police to shut down a busy highway was not an explosive device.
U.S. 77 - also known as Broadway Extension - was shut down about noon Wednesday after Oklahoma Gas and Electric Co. employees found a fence cut and a box with what appeared to be a threatening note attached.
Capt. Patrick Stewart says the box turned out to be a toolbox left at the scene by a contractor. He says there was no note, but someone had written words of a suspicious nature on the toolbox. The roadway was reopened shortly after 2 p.m. OG&E spokesman Brian Alford says crews are trying to determine if there was any damage at the site.
