Cambridge Police are hoping to identify and locate a person responsible for three separate incidents of sexual assault over the past eight months.

In each case, women told police a man approached them on the street, grabbed them, then fled on foot – in one case, laughing as he ran away.

Cambridge Police on Friday released surveillance videos and photos of a person they describe as a possibly Hispanic male, between 5ft 3 and 5ft 8in, of medium build and carrying a backpack dark.

Photos and videos show a man wearing a mask and carrying a black backpack, rolling down a sidewalk and through a parking lot. He was also seen going through an MBTA turnstile.

The unidentified man is suspected of a series of indecent assaults. According to police, the first reported incident occurred around 9 a.m. on February 10. In this incident, a man approached a 35-year-old Cambridge woman from behind near Mason Street and Phillips Place and put his hand on her bottom. The suspect then reached for the front of the woman and touched her groin area. The suspect then ran to Brattle Square.

The second incident occurred around 8:40 a.m. on April 13, when a 47-year-old Somerville woman was physically and sexually assaulted near the Porter Exchange mall at 1815 Massachusetts Ave. This woman told the police that she was walking down Roseland Street towards Massachusetts. Avenue when she felt someone approach her quickly. After trying to pull away, the suspect pulled her skirt up and fingered her buttocks. When she turned to confront the attacker, he fled.

The most recent incident occurred around 3.20pm on August 24, when a 19-year-old Cambridge woman said she was assaulted near Prescott Street and Broadway. Police said they responded to the spot after a man came from behind the woman and grabbed her by the chest. When she turned around, the suspect laughed and ran towards Prescott and Cambridge Street. Police said they arrested someone who matched the description of the attacker, but officers determined he was not the culprit.

Police say the suspect has “a unique and noticeable gait” as CCTV shows him running on his tiptoes. Cambridge Police sent an advance public notification about the suspect in April, along with surveillance video. Police said they received and investigated several reports, but could not find a suspect.
