Billings Public Schools superintendent Terry Bouck addressed threats against schools on social media on Wednesday night in the wake of a Florida school shooting.
"Tonight it came to my attention that there are threats toward schools occurring on social media," he wrote in an emailed newsletter calling the threats a hoax. "It is believed that these threats are a viral, nationwide issue and are not specifically directed at Billings Public Schools."
The school district will still add an "additional police presence at our high schools, as well as additional security observation at all of our schools."
Montana has seen a rash of reported school threats since the shooting that killed 17 people on Feb. 14 at Marjory Stoneman Douglas High School in Parkland, Florida.
A high school student in Helena was removed from class after posting a Snapchat video with a pistol. The video does not threaten anyone, school officials said.
Bouck addressed violent threats the day after the shooting as well, emphasizing the importance of reporting troubling behavior.
"The best line of defense is certainly communication between us all," he said last week.
