New England town plagued by rampaging man unleashing series of unprovoked attacks

Residents of Waltham, Massachusetts, are on edge after police said at least 10 men have been targeted by a mystery assailant in a string of unprovoked assaults that have occurred since November 10.

“Waltham police are using all means necessary to bring these cases to an end as quickly as possible,” Detective Sgt. Steve McCarthy said in a statement.

McCarthy said the latest attack occurred around 8 p.m. on Friday when a culprit came up behind a man walking on a residential street, hit him in the face with a blunt weapon and ran off under the cover of darkness. As in the other cases, McCarthy said the person responsible for the serial assaults appears to be lying in wait and attacking victims by surprise.

On Saturday, police released surveillance video of an individual they described as “a suspect in the string of recent assaults around Waltham” and urged the public to contact them with any information on the person’s identity.

Investigators only have a general description of the assailant, saying he appears to be a Black male, 5-foot-6- to 5-foot-10-inches tall and 160 to 180 pounds.

Initially, the assailant appeared to be targeting residents of an apartment complex but has since spread out across the community of roughly 63,000 people, attacking several recent victims in the city’s downtown area, according to police.

Police also took the unusual step of making reverse 911 calls to alert residents of the city, cautioning them to be vigilant and remain aware of their surroundings, especially after dark.
