A 21-year-old man was slashed in Washington Square while trying to play peacemaker, police said.
The victim told police he observed a man and woman fighting in the park at around 3 a.m. Saturday and then “tried to intervene” but ended up fighting with the male.
When the victim fell to the ground, the woman held him down and the man “pulled a knife and slashed him on the elbow and back,” police said.
The victim was taken to Bellevue Hospital in stable condition, cops said. The couple, both in their 30s, ran off. There are no arrests.
