Police in Hot Springs, Arkansas, have evacuated about 20 homes after a man mistook a Civil War-era land mine for a cannonball and took it home.
On Thursday afternoon the U.S. Air Force Bomb Squad was looking for a place to explode the ordnance.
Police spokesman Cpl. Kirk Zaner said a Hot Springs man dug up what he thought was a cannonball near Danville. The man put the 32-pound land mine in the back of his pickup and drove about 65 miles home.

After researching pictures of Civil War-era weapons, the man called police to say he thought he found a land mine with a pressure sensor fuse. Zanier says the Air Force bomb squad X-rayed the device and found what could be explosives inside.
