A fight that broke out at a Halloween party in Hudson, N.H., ended with stabbings that police say are not life-threatening.

Hudson police said they were called at 1:15 a.m. Sunday to a disturbance with a reported stabbing at a residence where a large Halloween party had been going on.

Police said a fight among several people broke out and escalated to where a knife was used. Police do not know why the fight started, but an investigation is under way.

A 20-year-old Nashua man was taken to a hospital with injuries from the fight. Two Massachusetts residents were treated at the scene for non-life threatening injuries to their arms caused by a knife and refused transport to the hospital.
