Police hunt trio for overnight armed street holdups in Cambridge; one victim injured

UPDATE: May be linked to attacks in Brookline, Boston.

Cambridge Police report they are looking for suspects for gunpoint holdups on at Putnam Avenue and Franklin Street and Arrow Street early this morning.

Police say two roommates were held up around 2:30 a.m. at Putnam and Franklin:

The victims observed a dark colored sedan traveling in the wrong direction on Franklin Street towards Putnam Avenue in their direction. When the vehicle was in close vicinity to the victims, two male suspects jumped out of the vehicle, pointed a small, dark handgun at them, and grabbed their purses and a cell phone. They then fled in the vehicle, which they described as driven by a third suspect and traveling in an unknown direction.

About a half hour later, a Harvard student reported he'd been robbed at gunpoint on Arrow Street while walking towards Bow Street:

The victim stated a dark colored sedan stopped and two males jumped out of the car and struck him in the face with what he believed to be a handgun and the head with an unknown object. The offenders ordered him to the ground. While on the ground, the offenders removed his headphones, money, and other personal items. The suspects then drove off with another suspect in an unknown direction. The victim suffered minor injuries, but refused medical treatment.

Police say the suspects are all black and in their 20s. They wore dark clothing and hoodies
