The stabbing happened Wednesday just as school was getting out and around the corner from the new Broadway production of "Groundhog Day."
Police say the suspect is a 16-year-old boy in a red hat, and he fled.
Authorities say a 15-year-old was stabbed twice in the back, a 16-year-old boy was stabbed in the stomach, a 17- year-old boy was slashed on his ear and an 18-year-old was wounded in the arm. Authorities say they suffered non-life- threatening injuries.
A witness tells The Associated Press that the fight escalated after two teens pummeled each other on the street.
