Police have arrested the man that they say shot five members of the same family over the weekend in Brooklyn.
Investigators picked up Curtis Peterson, 23, in Massachusetts.
Police say he opened fire on the family members Saturday afternoon in Bushwick.
Police say it started because the daughter of one of the victims had complained to him that Peterson was harassing her.
When the father confronted Peterson and a group of friends, police say Peterson pulled the gun.
Peterson is awaiting an extradition hearing and will face charges when he's brought back to New York.
