Seminole, Oklahoma - The Oklahoma Highway Patrol bomb squad spent several hours at the Seminole Walmart Wednesday morning, inspecting something that looked like a pipe bomb.

A store employee called police around 7 a.m. after finding a pipe with wires coming out of it. Walmart was evacuated for more than three hours while the bomb squad inspected the device.

They determined the device wasn't an explosive, but it was made to look like one. Because the object wasn't dangerous, the store reopened.

The Seminole Police Department is examining store surveillance video to determine who left the suspicious device.
