Another teen was busted for forcing a fight between two grade-school girls in the Bronx that was captured on YouTube video, authorities said.

The 14-year-old was charged as a juvenile with endangering the welfare of a child, cops said.

Sources said she may be the sister of the 6-year-old victim, but it was not immediately clear and the two had separate names.

One other older girl is still being sought in the case, authorities said.

Two other girls, 14 and 15, were previously charged with child endangerment, police said.

The disturbing video showed the two youngsters, 6 and 7, hitting each other and grabbing one another’s hair at Poe Park on Jan. 3 as older girls giggle and egg them on.

The video has since been taken off of You Tube.

The fight may have stemmed from a feud between two older girls over candy, sources said.
