Two teens are under arrest for allegedly encouraging two little girls to fight.
A video shows the older girls, ages 14 and 15, telling a 7-year-old and 8-year-old to shove and slap each other.
The incident happened on January 3 inside Poe Park in the Bronx.
According to sources, the sisters of the two girls involved egged them on in order to settle a dispute from the week before.
Someone at the park took cellphone video and uploaded it to YouTube.
The 14 and 15-year-olds are charged with endangering the welfare of a child.
