David Mueller, the deejay who was fired from KYGO radio in Denver after being accused of groping Taylor Swift, isn't off to a very smooth start at his new radio gig.

TMZ tells us that, even though he moved more than a thousand miles away to start a new job in Mississippi, he got a bomb threat this Wednesday, which was only his third day on the job.

Once Mueller was forced to evacuate the building, we learned the threat was empty.  No arrests have been made.  Someone else at the station says the threatening e-mail was "directly related" to Mueller's hiring.

Mueller was convicted last summer of reaching under Taylor Swift's skirt after a concert and grabbing her rear end.
