The Fort Smith Bomb Squad responded to a report of a suspicious backpack at the Walmart Supercenter on West Cherry Street in Alma.
Alma police were called because of the item and when officers reviewed the surveillance video they noticed a man come into the store and later place the backpack down in what officers thought was a suspicious manner.
Alma officers requested the assistance of the Fort Smith Bomb Squad, which investigated the backpack. It was found to be full of camping equipment.
Authorities said they believe they know the identity of the man who left the backpack and think he simply forget the bag when he left the store.
