WALTHAM (CBS) – Waltham Police released two videos on Saturday of someone they would like to identify in connection to “random, unprovoked assaults” that have taken place around the city in recent weeks.

Police say at least 10 people in the city of Waltham have been assaulted at different locations since Nov. 10. The most recent one occurred around 8 p.m. on Friday night near Chestnut Street and Sterns Street, according to Waltham Police Detective Sgt. Steve McCarthy.

The possible suspect, captured in the newly-released videos, is walking on Prospect Street wearing a dark coat, sneakers, and light blue pants.

People on Moody Street, which is about a half mile away from where the Friday night attacks were, say they’re afraid to go out at night.

“A little bit nervous, yes,” said one man, “Just be aware of people’s surroundings.”

The attacks have occurred at various times between 5:30 p.m. and 11:30 p.m. The victims have been alone and struck with a blunt object.

Initially, the attacks were going on at the GardenCrest Apartment Complex in Waltham, but have since occurred in other areas.

A Waltham resident who was attacked at the GardenCrest Apartment Complex told WBZ-TV in Spanish that he is afraid to return to the area he was assaulted.

“I came to smoke here in the back and suddenly somebody came from my back and hit me with something. Something heavy,” the resident said through a translator.

Waltham and State Police have been out patrolling the city, especially GardenCrest Apartments.

One woman says Waltham isn’t the place she’d expect this type of violence.

“Until the suspect is caught, I will be more cautious,” the woman said.

A local gun shop owner told WBZ-TV that people have been coming in asking for pepper spray to protect themselves.

Anyone with information is asked to call Waltham Police at 781-314-3600 or at their anonymous tip line, 781-314-3636.
