Officers are searching for a cab driver accused of sexually assaulting a woman near Tompkins Hall on 23rd and H Streets early Saturday morning.
The woman had hailed a cab from Georgetown to Foggy Bottom, and reported that the driver tried to have sex with her after pulling over in front of the hall. She got out of the van and ran to a pedestrian, who activated the blue light emergency system and alerted the University Police Department.
The University sent out an alert about the incident at about 12:50 a.m. Saturday morning.
The suspect, a heavy-set black man in his 40s, was last driving north on 23rd street in a silver van with tinted windows, according to the alert.
The Metropolitan Police Department is leading the investigation, University spokeswoman Maralee Csellar said, and officers are searching the area.
Csellar said the woman was not a GW student. The MPD public information office did not return requests for comment.
Under the federal Clery Act, universities must issue warnings about incidents that pose an immediate threat to the campus community. Schools are also required to report sexual assaults – and all crimes that occur on campus – to the Department of Education.
