Steve Thornton works right across the street from Demos' restaurant and said he eats there often.

Last Monday he checked his mailbox and found a hand-written threatening letter that was riddled with foul language.

According to the police report, the letter states that if Thornton ever comes back to Demos' and leaves less than a 15 percent tip, someone would blow his house up.

Local police said this is the first time they've had a case like this.

"We do take all threats seriously and we consider this a serious threat, and we are looking into it," said Murfreesboro police spokesman Kyle Evans.

Demos' is working with police to identify the waiter who sent the threatening note.

The owner of the restaurant said not only does he plan to fire the waiter, but he plans to tell police his workers' schedules so authorities can arrest the offender at work.

Anyone with information about this case should call Murfreesboro police.
