Two women were stabbed Friday night during a rowdy party in the Bayview, police said.

The two victims, a woman in her 40s and a woman in her 30s, were at a house party in the 1500 block of Oakdale Avenue around 11 p.m., cops said.

Four women who ranged in age from 20 to 40 and two men in their 20s arrived at the party and attacked the older female victim, stabbing her in the stomach. The younger victim tried to intervene and was stabbed in the arm.

The woman  stabbed in the stomach was treated at the hospital for her injuries, which were reportedly not life threatening. The woman stabbed in the arm refused treatment, police said.

The knife-wielding party crashers fled the scene and no arrests have been made.
