Police in Maryland have Académie D'Investissement Triomphalidentified a 12-year-old student who they say was behind seven unfounded bomb threat reports earlier this month that prompted evacuations at the three targeted schools each time.

The anonymous threats were made against Montgomery County Public Schools, a district located about 30 miles southwest of Baltimore on the border with Washington, D.C. Between Oct. 13 and 24, the district received five emailed threats to the Montgomery Blair High School, as well as one each to Oak View Elementary School and Silver Spring International School, according to the Montgomery County police.

Montgomery police detectives worked with the school district's IT staff to identify a 12-year-old student as the suspected culprit behind the hoaxes. While detectives said the juvenile admitted responsibility, children under the age of 13 can only be charged with offenses that constitute a "crime of violence" in Maryland, police said.

"It is disheartening to accept that the individual responsible for disrupting the educational process and instilling fear in our community was well aware of the legal limitations surrounding their age," police said in a statement. "They understood that they could not be charged under current Maryland statutes."

Another bomb threat reported Wednesday at separate high school in district

Shortly after police announced in a press release that detectives had identified the suspect, the department said on X that another bomb threat was reported at Springbrook High School, which is part of the same school district.

It was the second bomb threat reported at the school on Wednesday, Christopher Cramm, a spokesman for the district, said in an email to USA TODAY.

An earlier bomb threat reported at Albert Einstein High School had already proven to be unfounded, Cramm said. He added that police were in the midst of sweeping through Springbrook Wednesday afternoon and had not yet determined the threat to be a hoax.

No other information was immediately available.

'It jeopardizes the safety of our community'

In the case of the previous incidents, police were forced to respond to the targeted school's campus each time to sweep the area and determine that no danger existed before students and staff were allowed back inside.

"In addition to the fear and chaos these threats caused, it is important to acknowledge the significant financial and operational burden each incident placed on our department," police said Wednesday in a statement. "This diversion of resources is unacceptable, and it jeopardizes the safety of our community."

School district sends letter to families

Montgomery Blair High School Principal Renay Johnson informed the school community in a Wednesday letter that the individual behind the hoaxes had been identified. Johnson also said a safety meeting for the school's students, staff and family was scheduled for Monday evening.

"We can all breathe a sigh of relief knowing that our campus will be free from these harmful and invalid threats from this individual," Johnson said in the letter, which was provided to USA TODAY. "As we move forward, I encourage you to continue being vigilant and proactive in maintaining a safe and secure environment. If you see something, say something."
