Newly released video shows a car thief dragging a cop during a Brooklyn chase — the spark for a dramatic clash between cops and two other people who had been racing with the thief.

Officer Raymond Buono, a plainclothes officer from the 70th Precinct, spotted the cars in a road race near the corner of Coney Island and Church Avenues in Flatbush around 2 a.m. on April 5, according to a complaint filed by the Brooklyn District Attorney’s office.

Both cars turned the corner without signaling, prompting Buono to pull over one of the drivers, 22-year-old Emmanuel Devallon. Devallon was driving a stolen 2016 Nissan Maxima with Virginia plates.

He brushed away Buono’s handcuffs, jumped back into the car and then stepped on the gas when the officer tried to pull him away from the wheel — dragging him, according to the Brooklyn District Attorney’s office. His white sneakers are visible as he struggles with the driver.

Another plainclothes officer, who also tried to stop Devallon, is seen after the car as it sped off with his fellow officer.

The occupants of the other car in the race — Akwasi Sakyi, 25, the driver, and Ashley Biggs, 21 — hopped out of their Honda CRV and stood between the cops and Devallon as they tried to arrest him.

Sakyi also pushed an officer at one point, prosecutors said.

“What are you all doing?” Biggs can be heard screaming multiple times, which Sakyi asks again later.

“Stand the f–k back!” an officer yelled.

“OK,” Biggs said at one point. “He’s OK.”

But when Sakyi attempted once again to get in the way of the officers arresting Devallon, trouble started again.

The video shows one officer grabbing Biggs by the arm and pushing her away.

Then the cops took Sakyi down to the ground.

Buono, whose pants were pulled slightly down from being dragged, joined the fray.

A K9 officer was also present, but the dog wasn’t involved in the scuffle.

Devallon was charged with assault, possession of stolen property, failure to signal, speeding, obstruction of governmental administration, and fleeing a police officer in a motor vehicle, according to the complaint. His car had been reported stolen by the Hertz rental car company.

Biggs was charged with obstructing governmental administration, marijuana possession and disorderly conduct, according to her complaint. Sakyi was also hit with those charges, as well as two speed-related offenses. Cops discovered multiple marijuana joints in the duo’s car, prosecutors said.
