A home invasion in Norwalk Monday sent three people to the emergency room with stab wounds.

The incident happened around 5 a.m. at 23 Charles St.

Police and witnesses say a woman enraged by her ex-boyfriend's recent marriage, came from N.Y. with two friends to stab her rival and the man who rejected her.

A brother of one of the victims says when another brother went to their aid he got stabbed in the arm.

Police say they arrested three women and one man after their vehicle was spotted in Greenwich. According to police, all four individuals face multiple charges including home invasion, which now carries a maximum sentence of 25 years in prison.

The victims were all treated and released from Norwalk Hospital.
