Metropolitan Police officers are investigating a threat of a weapon on campus in the 900 block of 23rd Street, a public information officer confirmed.

MPD first received a call for the threat at 12:08 p.m. and arrived on scene at 12:11 p.m., MPD public information officer Anthony Clay said. The call was for an individual who had a weapon.

MPD officer Paul Metcalf said the department was still investigating the incident at about 3:15 p.m. In an infomail message sent out at 3:30 p.m, Senior Associate Vice President for Safety and Security Darrell Darnell said at about 3:30 p.m. that there was no individual on campus with a weapon, but there was a “non-specific threat against George Washington University doctors.”

University spokeswoman Michelle Sherrard initially repeatedly declined to comment on the incident, referring all questions and comments on the type of threat, its extent, and the University Police Department’s involvement in responding to MPD.

UPD officers also responded to the scene, according to the e-mail, and are “continuing to work closely with MPD regarding this incident.”

Sherrard later added, “The [Medical Faculty Associates] received a non-specific threat against doctors. MPD is on the scene and investigating. We have no evidence that someone is on campus with a weapon. MPD is the lead and should be contacted with questions.”

Public information officer Hugh Carew said at about 6:40 p.m. that MPD was no longer on scene. Sherrard had not yet responded on the disposition of the case.

The 900 block of 23rd Street is near the Avenue and the GW Hospital.
