A Dorchester woman was slashed in the face with a knife after a 15-person fight broke out on Massachusetts Avenue around 8 p.m., following the Cambridge Carnival.

According to police, a group of women were walking in Central Square after the festivities when one member of the group began fighting with another group of women on the street. During this altercation, a woman described as a heavyset black woman with a purple shirt and shorts in her late teens or early 20s allegedly pulled out a knife and slashed another woman in the face.

The women told police they had never seen the suspect before.

Police were advised that the incident may have been caught on cameras.
