WASHINGTON (KNX) — The FBI has identified six minors as persons of interest in a series of threats made against historically Black colleges this week.
The minors are believed to have used sophisticated methods to disguise the source of the racially motivated threats, which were made at the start of Black History Month Tuesday, law enforcement officials told NBC News.

More than a dozen Historically Black Colleges and Universities (HBCUs) were targeted.
Howard University in Washington D.C. was among the first to issue a shelter-in-place order early Tuesday after the school and several other HBCUs received similar threats. The university was cleared later Tuesday after the threat was found to be unsubstantiated.
The FBI did not disclose much information about the teens other than that they were located around the country.
The FBI released statements on Monday and Tuesday, saying it was taking action against this latest string of bomb threats.
“The FBI is aware of the series of bomb threats around the country and we are working with our law enforcement partners to address any potential threats,” the FBI said.
“As always, we would like to remind members of the public that if they observe anything suspicious to report it to law enforcement immediately.”
