The Farragut Post Office was closed for about hour and a half on Tuesday, after the discovery of a "suspicious package."
According to the Postal Inspector, around 10 am, a box was spotted on top of a mailbox outside the post office.
Officials called the Knox County Sheriff's Office, and the bomb squad responded to check the item out.
They safely detonated to be sure. Turns out, the package contained a harmless "household item."
The post office is now back open.
