WALTHAM, Mass. (WBZ NewsRadio) — The Waltham Police Department has released more surveillance footage of a person they believe is connected to a series of attacks in the city in recent weeks.
The videos on the department's Facebook page show the suspect running in the areas of Prospect Street and Bedford Street.
The release comes after nearly a dozen reports of random night time attacks on pedestrians in just over two weeks. Police said the attacks have all occurred some time between 5:30 p.m. and 11:30 p.m. in several different parts of the city.
Police also released two videos on Sunday of a potential suspect in the attacks. The footage shows a person in blue jeans, white sneakers and a dark sweatshirt.
"The Waltham Police are looking for the public's assistance in identifying the individual in the attached video, concerning the recent assaults in Waltham," police said on Sunday. "If you have ANY information about the identity of this individual, or the assaults themselves we urge you to call us at 781-314-3600 (Option 4) or the anonymous tip line at 781-314-3636."
The Department also said on Tuesday that investigators are offering a $5,000 reward to anyone with information that leads to the arrest and conviction of the suspect behind the assaults.
According to Waltham Police Lieutenant Robert Robillard, the physical descriptions of the suspects have ranged between black and white males of varying heights.
"The victims have been alone, and either struck from behind, or struck without provocation," Robillard said in a reverse-911 call to residents.
Waltham Police are continuing to urge residents to be aware of surroundings, especially when out after dark, and not to be distracted by their cellphones or headphone when walking.
