Police have arrested a man for pepper-spraying four people aboard a city subway during a dispute.
A 1-year-old child also was injured when one of the victims dropped her while passing her over to the mother.
The incident occurred on a D train bound for Coney Island Thursday evening.
Police say the pepper spray hit the 15-year-old mother, her 16-year-old sister and the 16-year-old boy holding the baby.
A nearby 21-year-old passenger also was sprayed.
Police say the dispute erupted after the 16-year-old boy confronted the suspect over a loud cell phone conversation.
The suspect was charged with criminal possession of a weapon, endangering the welfare of a child and reckless endangerment.
The baby is listed in stable condition at a hospital. The others suffered minor injuries.
