FLORIDA (WTHR) — A sheriff's deputy in Florida has resigned after sending a fake bomb to a co-worker.

The incident happened earlier this week when another Florida sheriff's deputy received a package through their inter-office mail.

Inside, there was a handwritten message that said, "Boom" along with a toy bomb.

Deputies evacuated the building and the bomb squad had to come in and check it out.

Afterwards, the deputy who sent the toy contacted his supervisor and told him about the joke and he resigned from his position the same day.

The sheriff says that was no laughing matter.
