D.C. Police spokesman Officer Hugh Carew says investigators found a DMT lab where chemicals could create a hallucinogenic drug. DMT stands for dimethyltryptamine. Officials thought it was a methamphetamine lab earlier Saturday.
Emergency crews responded about 6:15 a.m. after a strange odor was reported. About 400 students were evacuated from Harbin Hall. Seven people were exposed to noxious chemicals, including three students.
Georgetown spokeswoman Julie Green Bataille says no one was injured and the rest of the campus is operating normally.
Carew says two of the suspects are students and one was a visitor. Local and federal agents are investigating.
