The woman who vandalized cop cars and a Brooklyn school with anti-NYPD graffiti has been arrested, police sources said.

Rosella Best, 36, was caught on surveillance video tagging PS 31 near Lorimer and Mesorole streets around 5:30 a.m. Aug. 26, according to police. “NAZIS=NYPD,” a vandal spray-painted, along with a swastika, on a police car.

She was arrested Monday and charged with aggravated harassment, criminal mischief as a hate crime, which is considered a felony, cops said.

The woman scrawled other hate messages on and near a school in Williamsburg: “NYPD pick on the harmless” and “NYPD pick on the innocent.”

Cop-hating and anti-Semitic remarks were plastered on vans and scooters near the school, the sources said.

A Rite Aid shop and a post office were also hit with the graffiti, according to police sources.

The blond, blue-eyed vandal was previously arrested July 16 after she threw a green drink in a woman’s face during an argument in a Brooklyn park on Kent Avenue and North 10th Street around 12:30 p.m., cops said.

She was charged with menacing, assault and damaging personal property in that case.

The 27-year-old victim told cops the juice got in her eyes, stained her outfit and ruined her cellphone, the sources said.
