A 17-year-old girl was arrested Wednesday in a bomb threat to Dunbar High School during a visit in February by Doug Emhoff, the husband of Vice President Harris, a D.C. police spokesman said.

       A motive remains under investigation and it could not be determined whether the Feb. 8 incident was in any way connected to Emhoff’s visit. Police at the time said the threat was called in to the front desk warning that people had 10 minutes to leave.

       The teenager was not identified because she is a juvenile. Authorities on Wednesday evening were still in the process of charging the teenager.

       Authorities evacuated the school in the 100 block of N Street NW in the Truxton Circle neighborhood, but found nothing hazardous. Emhoff was escorted out of the school by the U.S. Secret Service.

       The incident occurred amid a wave of bomb threats made against schools across the District and in Maryland, including at eight D.C. schools on a single day.

       In February, D.C. police said two teenagers were arrested in connection with bomb threats at several of those schools in the District. Police at the time said they did not think the threats made at local high schools were linked to threats made against historically Black colleges and universities across the country.
