School is back to normal at Fred Moodry Middle School in Anaconda, a day after students were evacuated due to a bomb threat.
Chief of Police Tim Barkell says the middle school was evacuated around eleven in the morning Wednesday.
According to Barkell, the letter "B" was written twice in marker on the bathroom wall.
The letters "O" and "M" were written in between the B's, spelling the word "Bomb".
Authorities and school faculty are continuing to take precautions around the school.
A search was conducted but nothing was found.
