The city plans to warn the female community in West Somerville of a sexual predator possibly lurking in the neighborhood.

Using Reverse 311, the city is able to reach hundreds of households, informing them of  situation such as the one in West Somerville, the Tufts University area. The calls were to have gone out to Ward 6 and Ward 7 residents. The message ‚Äì to beware of a man described as being between 5‚Äô5‚Äù and 5‚Äô10‚Äù tall, having a heavy build and medium complexion, wearing a hooded shirt or jacket and driving a burgundy or red SUV.

The Tufts University’s student newspaper reported that there have been four attacks in the last month.

According to a memo sent out by university police to the campus community, three of those sexual assaults occurred with in a 10-day timeframe. Two of the incidents were similar. On April 10, a woman told police she had been grabbed by a man, wearing a black hooded-sweatshirt. That was Winthrop Street. Then a similar situation took place and was reported on North Street.

On Friday, April 20, another case was reported to police in Medford. A woman told police she was walking from the bus stop on Boston Avenue and Winthrop Street when she was taken at knifepoint into a driveway and then sexually assaulted. Following the attack, the woman  was forced into a red SUV with a black top and black interior. Her attacker allegedly drove around back streets for some amount of time before releasing her from the vehicle, according to the memo.
