Two people were arrested amid a chaotic anti-police protest in Brooklyn, including a woman who scrawled “PIGS” on a cop car, authorities said.

The graffiti incident comes a day after a large crowd sneered at police officers struggling to remove trash thrown onto their car in Brownsville.

Sarah Autz, 25, was arrested after she allegedly wrote “PIGS” in marker. Pictures from the protest show other vandalized police cars, with one saying “NYPD KKK.” An MTA bus was also defaced with “F–k NYPD” and “NYPD KKK.”

Another man, 22, was issued a summons after allegedly spitting at officers, police said.

Over a thousand anti-police protesters occupied the streets of Downtown Brooklyn during an unauthorized demonstration against an NYPD crackdown on fare evasion. The protest was also a response to the two controversial police arrests in Brooklyn subway stations that were caught on video.

Protesters blocked traffic as they marched down the streets with large banners that read “F–k the police” and “Don’t let these pigs touch us.”
