Police have charged a pair of middle school students in connection with a false school shooting threat made last week in Maryland, authorities said.

A parent called officials at Aberdeen Middle School on Dec. 3 after seeing a post on social media warning students not to go to school the next day because a student had threatened to shoot it up, police said.

Investigators later determined the threat was not credible and that the student blamed for it never made the threat, officials said.

Police charged an eighth-grade student with making a false statement to a peace officer and charged another with disturbing school operations in connection with the threat, officials said.

“The Aberdeen Police Department encourages students and parents to report threats of violence to our children and schools, as safety is our main concern, however at the same time, false reports or the posting/reposting (of) threats on social media will not be tolerated,” police said in a statement.
