KANSAS CITY, Mo. (AP) -- The federal courthouse in Kansas City is reopening after authorities say nothing explosive was found inside a suspicious-looking cooler.
The courthouse was evacuated and employees were sent home Monday after the soft-side cooler was found near a garage door where prisoners are brought into the building. A note on the cooler said the contents would explode.
Bomb and arson detectives were called in, but authorities said all that was found inside the cooler were phone books.
The federal courthouse in Kansas City has been evacuated after a suspicious package was found with a note warning of explosives inside.
Authorities say a soft-side cooler was found near a garage door where prisoners are brought into the building with a note saying the contents would explode. U.S. attorney's spokesman Don Ledford says the courthouse was evacuated and employees were sent home for the day.
Police spokesman Rich Lockhart says bomb and arson detectives have been called in, and a bomb robot is being used to examine the package.
Investigators have blocked off the area and are not allowing vehicles or pedestrians near the building.
The U.S. Marshal for the Western District of Missouri, Mauri Sheer, says the all-day evacuation is "unusual." But he added, "We normally don't run into this."
