Police are searching for the suspect in an armed robbery that took place on the UMass Boston campus just after 11:30 a.m. today, according to university officials.

A man indicated to a student that he had a firearm at 11:33 a.m. between the Quinn Administration Building and the Clark Athletic Center, stealing the victim’s purse and fleeing in an unknown direction, according to an email sent to students at 1:15 through the UMass Boston Alert System. The victim was unharmed.

The suspect is described as a white male, 5’9” of medium build wearing a black winter hat with a green bandana covering his face. He also wore a beige jacket and a backpack. It is not clear if the suspect is a student.

Following the incident, UMass Boston police swept the campus as well as adjacent Bayside Expo Center and the JFK/UMass MBTA station, UMass Boston spokesman DeWayne Lehman told the Reporter. While the incident falls under UMass Boston Police’s jurisdiction, nearby Boston Police stations have been made aware of the incident and the suspect’s description.

Anyone with any pertinent information is asked to contact the UMass Boston Police Department at 617-287-7780. Students are also cautioned to “not to stop and talk to strangers, to walk in well-lighted areas, and to report any suspicious activities or encounters to the UMass Boston Police Department,” according to the Alert System email.

A previous version of the story incorrectly stated that the suspect brandished a weapon. No firearm was shown to the victim, police say, but the suspect indicated he was in possession of such a weapon.
