WASHINGTON (WNEW/AP) — A ricin scare at Georgetown University is being investigated, authorities say.
University officials notified D.C. Fire and EMS of a report of possible ricin in one of its on-campus residence halls early Tuesday morning, according to a D.C. Police spokesperson.
An initial field test for biological agents in the residence hall came back negative. Authorities deemed no immediate risk in the area and students were told they could remain in all campus buildings.
FBI spokeswoman Jacqueline Maguire says the substance found was initially reported to be ricin, but they are conducting further testing of that material.
D.C. Police and federal authorities are interviewing a person possibly linked to the substance.
