A school-safety agent was arrested Sunday for pummeling a pal and threatening her with a knife during a dispute in Brooklyn, cops said.

Rahdasia Davenport, 22, was busted just before 4:30 a.m. at her East New York home for allegedly punching her friend multiple times in the face, scratching her on the back of her neck and flashing a knife, police said.

Cops said Davenport and her 23-year-old friend began arguing inside the Dumont Avenue residence around 3:30 a.m. when the dispute turned violent. It was not immediately clear what the pair was arguing over.

The school-safety agent has worked in her role for approximately a year, according to SeeThroughNY.

She was charged with menacing, assault and criminal possession of a weapon.
