Law enforcement agencies say they thwarted a potential school shooting in Washington, DC, on Wednesday – the same day as the horrific shooting at a Catholic grade school in Minneapolis – arresting a juvenile and recovering multiple firearms.

The ATF’s Washington Field Office announced in a social media post that its agents, alongside DC’s Metropolitan Transit Police officers, “Quickly intervened and interrupted what could’ve possibly led to a school shooting incident in #DC.”

The agencies did not reveal the name of any school targeted beyond identifying it as a public school in the district.

In a joint statement to CNN, the Transit Police and ATF said the police department’s “Criminal Investigation Division found an alarming social media post referencing a potential threat to a DC public school.”

A search warrant was executed by MTPD and ATF officers on Wednesday “at a residence where multiple firearms were recovered” and “a juvenile was placed under arrest,” according to the statement.

The ATF released a photo of the firearms, displaying six handguns, six magazines and two boxes of ammunition.

Authorities said the incident is still under investigation and did not provide any additional details about the case or what was said in the social media post that referenced a potential threat to a DC school.

A DC Public Schools spokesperson told CNN in a statement, “We’re not currently tracking that any DC Public Schools students have been apprehended in relation to this incident.”

During a press conference at the White House Thursday, press secretary Karoline Leavitt mentioned the arrest while touting the Trump administration’s law enforcement surge in DC, saying that “there was an arrest of a juvenile right here in DC, in Ward Seven,” an area of the city that struggles with high rates of violent crime.

Leavitt said the juvenile was arrested “for threats to kidnap and injure, receiving stolen property, possession of a large capacity feeding device, unlawful possession of firearms and ammunition.”

CNN has not been able to identify an attorney for the juvenile. CNN has reached out to the DC attorney general’s office for additional information.
