Random Knife Attack On Upper West Side Leaves 4 Injured

An "emotionally disturbed man" stabbed four people on Manhattan's Upper West Side Tuesday morning, NY 1 reports.

The victims include a 3-year-old boy, who was stabbed in the arm.

The attack - which occurred shortly before 8 a.m. along a bike path near West 63rd Street in Riverside Park - appears to be random, and police took the suspect into custody, according to Gothamist.

One female victim is in serious condition. Victims were transported to local hospitals after the attack.
