ST. LOUIS • A woman was slashed with a box cutter after a fight erupted between two women as they picked up their children from a St. Louis charter school Tuesday afternoon.

One woman punched the other, and the second woman pulled out a box cutter, police said. She cut the first woman in the neck and chest.

The victim of the cutting was taken to a hospital, police said. Her condition was not available but police said she was stable.

The woman with the box cutter was arrested at the scene. Police say they plan to charge both with assault.
