The Boston University community was put on alert for a third time in two weeks on Friday after a victim was robbed at gunpoint by three suspects.

According to Brookline Police, the victim, a recent college graduate, was allegedly approached by three black teenage males around 5 p.m. The suspects flashed a handgun before robbing the victim and then fleeing on food towards Commonwealth Avenue.

The victim wasn’t harmed during the robbery and Brookline police are investigating, according to the report.

Boston University students were sent an alert about the incident, which occurred at St. Paul Street and Thatcher Street in Brookline.

Just a few weeks prior, three suspects allegedly robbed “local college students” at gunpoint on September 25, marking the second armed robbery in the Boston University area in less than three days.

That incident occurred at the intersection of Egmont and St. Paul Streets at approximately 5 p.m., according to an advisory sent out to students at the time of the second robbery.

The first armed robbery resulted in students from Boston University having their smartphones stolen, according to reports.

No students were reported injured in any of the cases.
