A Brentwood woman has been charged with endangering the welfare of a child after she helped her teenage daughter fight another girl on Thursday, Suffolk police said.

Police said Dorka Lopez, 41, drove her 15-year-old to Regis Park, on MacArthur Avenue, to fight another girl the same age. Police said the mother watched the girls fight and at one point, grabbed the other girl's head and shoved her to the ground.
