A high school student in South Carolina was arrested Thursday and faces charges for that threat.
Another high school student in Vermont was arrested Thursday night for allegedly making shooting threats.
Meanwhile, the Volusia County Sheriff's Office said it will provide an increased presence at several schools and is prepared to respond to all reports of threats and suspicious activity.
Deputies responded to Pine Ridge High School on Thursday afternoon after a student found two bullets stuck between two mats in the school’s weight room. No weapon was found and there were no threats of violence.
A 17-year-old student was questioned because he had been spotted sitting near the area where the ammunition was found. However, the student had no knowledge of the bullets.
“We treat every one of these incidents seriously and we will do everything we can to make sure every student is safe at school, especially in today’s heightened state of alarm,” Sheriff Mike Chitwood said. “I want to encourage everyone to report suspicious activity when they see it. Don’t hesitate. If you see something, say something, and we will do something.

In Massachusetts, the principal at Durfee High School in Fall River said in an audio message to parents Thursday the school would have an elevated police presence, with random bag checks conducted and other, unannounced security measures in place.
Several Durfee High School students reported the post to police after seeing it.
Principal Matt Desmarais said the threats are not seen as credible, but school officials are acting cautiously and appreciate the students who spoke up.
"I want to reinforce the statement, 'See something, say something,'" Desmarais said. "This cannot be stressed enough. I am appreciative of those who brought this to our attention today. It is the students who choose to do the right thing each and every day who truly represent the Durfee High School.”
