Harvard Warning Students After Off-Campus Attack

BOSTON (CBS) --  Harvard University is telling students to be on alert after a student was allegedly assaulted off-campus.

It happened just after 1 a.m. Monday around 300 Beacon Street in Somerville. The student, who was walking home from Porter Square MBTA Station, told police she screamed and fought off her attacker.

She was later able to describe him as a thin black man, in his thirties, six feet tall, clean shaven, and wearing dark clothing. Police have provided a sketch of the suspect.

The incident is being investigated by Somerville Police but Harvard Police are asking students, faculty and staff to call police if they see anything suspicious.

Officials say the incident is similar to an assault that was reported in Cambridge last week.

Last Wednesday, a woman was assaulted on Richdale Ave. while walking home from Porter Square MBTA Station.

Police are investigating whether the two incidents are connected.

Harvard Police also sent out an alert Wednesday after a man reportedly exposed himself to a grad student.
