Authorities in Massachusetts are asking for the public's help in identifying a suspect in a sexual assault earlier this week.
State police released three surveillance images of a man on a bicycle they believe attacked a 24-year-old woman along Memorial Drive in Cambridge.
The suspect is described as a white man in his late 20s to early 30s. He's described as having a stocky build and blonde or light brown hair and was wearing dark clothing at the time.
Police say the suspect was riding a bike before and after the attack.
Anyone with any information is asked to call state police at (617) 740-7875.
The victim, a Boston woman, had left a Cambridge bar and was walking near the Weld Boat House on Memorial Drive when she was allegedly approached by the suspect, who physically and sexually assaulted her when she tried to walk away.
Police say that when the woman screamed for help, nearby witnesses ran toward her, and the suspect got back on his bike and fled.
The woman was taken to St. Elizabeth's Hospital for treatment.
State police say they're also investigating whether several other reports of a suspicious person in the area is the same person.
As a reminder, the Cambridge Police Department offers a self-defense class for women who live, work and study in Cambridge. If you are interested in signing up for a future class, please call the Community Relations Unit at 617-349-3236.
