PLUM (KDKA) — Officials have canceled classes today in the Plum Borough School District due to a “non-specific potential threat.”

According to district officials, the possible threat was reported to the state’s Safe2Say program.

Plum Borough Police are now investigating.

On their website, the district posted a message saying:

“In an abundance of caution and until the investigating can be thoroughly completed, the District has chosen to close the Plum Borough School District on Monday, Jan. 27, 2020.”

Back in the spring of 2017, the district dealt with six bomb threats in less than a month.

Eventually, the frustration of parents grew and they let their concerns be known at a school board meeting.

“What’s it going to take for them to take safety seriously in these schools? We’ve had enough drills, six bomb threats, gun threats, junior high, elementary and high school. When’s enough, enough?” said parent Chad Salerno that night.

The district announced several measures to stop the problem. In all, five people would face charges for the threats. They would be charged with terroristic threats and disorderly conduct.

The Plum Borough Police Department said they “have developed juvenile suspects in the case.”

The suspects are not permitted to attend school or be on school grounds, police say.

Students will return to school on Tuesday, the district said.
