Several alleged school shooting threats are creating a tense atmosphere in Lower Bucks classrooms. And rumors on social media are contributing to local fears.

Authorities brought charges against two students at the Bristol Borough School District earlier this week. The Council Rock North community is also on edge, but no arrests have been made.

One juvenile allegedly made threats against Bristol Middle/High School Sunday night. Another student alerted authorities through the Safe2Say Something tip line of the plan.

Within hours of the tip, the Bristol Borough Police Department had a teenage male in custody. He faces charges of making terroristic threats and disorderly conduct.

Investigators said they did not find any weapons in connection with the alleged threats. But school officials still closed the high school Monday “out of an abundance of caution.”

Then reports came out of another student who allegedly made other, unrelated threats Monday to shoot up Snyder-Girotti Elementary School.┬áThe Bucks County District Attorney’s Office has brought charges against the sixth grader, including two counts of making terroristic threats.

However, it turned out this second situation was more complicated. Superintendent Thomas Schafer explained the incident in a letter to parents

“A student made an inappropriate comment in a classroom. The teacher notified the office. The student was immediately removed from the classroom and was sent home in the custody of their parent.”

The student had brought a fishing knife to school and another student submitted a Safe2Say tip. A message from the school district said, “at no time was anyone in danger.”

All Bristol Borough schools are open for class Thursday.

The threats and uncertainty in Bristol Borough may have contributed to an atmosphere of fear for parents and students at Council Rock North High School.

Many students at CR North chose not to go into class this past Monday as a result of perceived threats. But the Newtown Township Police Department said this was mostly thanks to false information spread on social media.

Last Friday, police received a tip from a student regarding a potential threat. The threat had allegedly been made several weeks ago.

Police noted they investigated, but “upon further analysis of the incident, and additional information from witnesses, a determination was made that no credible threat was found.”

School officials tried to inform parents of the results of the investigation, but social media had a further reach.

Then another tip added fuel to the fire. A student submitted a report to police Monday evening of a perceived threat.

Police found it “non-factual and not a credible threat to the school district or students.” Investigators also found this unrelated to the initial matter.

Regardless, Council Rock school officials chose to hold classes at the high school virtually Tuesday.
