LOUISVILLE, Ky. (AP) — Authorities say papers were all that was in an unattended briefcase found on the steps of a federal courthouse in Louisville.

FBI spokesman David Beyer says the Louisville police bomb squad used a mechanical device to look inside the briefcase Monday afternoon. He says police were able to determine the bag didn't contain any type of explosive device.

A two-block section in front of the courthouse was closed down around shortly after police were called. A courthouse employee noticed the accordion-style briefcase with a note taped to it and alerted authorities.
