CAMBRIDGE, MASS. >> Police say a "love triangle situation" may have caused a group of up to eight men to attack a pregnant woman near Central Square in Cambridge.

Cambridge police spokesman Jeremy Warnick says officers were dispatched to the area of Massachusetts Avenue and Pleasant Street around 1:50 p.m. Tuesday following reports of the assault.

The woman was involved in a large altercation with two former and current romantic partners when the group of men began punching and kicking her in the stomach.

The victim, who hasn't been identified, is in her early 20s. Warnick says she told officers that she's four months pregnant. After initially refusing medical attention, WHDH-TV reports the woman eventually went to a local hospital for treatment.

Police have identified several suspects but no arrests have been made.
