As if the gun violence lately weren’t bad enough, three people were sliced with a box cutter at the Sutphin Boulevard–Archer Avenue subway station in Queens this morning, CBS reports, but the injuries are not thought to be life-threatening. A 22-year-old woman is in police custody, and her motive remains unclear, although NBC reports that “the attack does not appear to be random and may have followed a dispute between two groups of people.”
