An anti-police activist was arrested Wednesday for reportedly tossing a flaming hat at an NYPD officer’s home during a protest over the officer’s alleged rough handling of demonstrators at an earlier rally.

Terrell Harper, 42, and other protesters showed up outside the officer’s home in Brooklyn Monday night after the officer “put his hands on protesters” during a separate rally at a police station a day earlier, Harper claimed on social media, the New York Post reports.

Harper was “with a group of protesters standing in the front yard, chanting for the officer to come outside,” an NYPD spokesperson said.

 “He then took a hat and lit it on fire and threw it,” the spokesperson said. He was reportedly targeting a window. Police did not say where it landed.

“It’s all about making them scared of us. It’s all about making them want to quit their f—ing job, you know what I mean?” Harper later bragged about the protest outside the officer’s house in a video he posted to Instagram. “Nothing can stop them from making us go back to that [cop’s] house.”
