Seven predominantly Black public high schools in Washington DC were evacuated after they received anonymous bomb threats on Thursday. However, police found no explosives. This comes a day after VP Kamala Harris’ husband Doug Emhoff was whisked away from a school following similar threats. 

Dunbar High School, the one Emhoff visited, Theodore Roosevelt High School, Ron Brown High School, KIPP DC College Preparatory, IDEA Public Charter School, Seed Public Charter School and McKinley Tech High School were the schools that had to be evacuated, the Metropolitan Police Department confirmed. The bomb threats were made via phone call.

In each case, students were evacuated and the building searched and “cleared with no hazardous material found,” the MPD announced on Twitter.

An eighth school, Friendship Public Charter School, also received a threat, but school was not in session.

Only a week ago, bomb threats were made to at least a dozen historically Black colleges and universities, or HBCUs, across the United States. 

“Americans have a right to be safe at work, in houses of worship and at school. We must stand up against any threat of violence in our communities,” VP Harris had said in a statement.

However, like Wednesday, no explosives were dound. The latest of the threats made to seven schools are being probed by the FBI. Washington police had said they are investigating this week’s threats to Dunbar, considered the first high school for Black Americans in the US.

The MPD said it was “working to thoroughly investigate these threats with the assistance of our federal partners” at the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Lewis Ferebee, chancellor of D.C. Public Schools, called the threats “disturbing incidents that we take very seriously.”

In a statement, Ferebee said the school system would work closely with MPD “regarding any threat made toward our schools, students, or staff.”
