A homeless, handcuffed accused turnstile-jumper kicked an NYPD cop so hard that she tumbled off a Harlem subway platform and onto the train tracks, a shocking video shows.

The officer — who was also spat on by by attacker, who claimed to be infected with the coronavirus — broke her wrist in the fall to the tracks, but was otherwise unharmed, sources told The Post.

The terrifying incident happened at the 125th Street station on Thursday evening as two cops tried to arrest the unhinged man, who began screaming at officers, begging them to injure him, according to a video posted online.

“I can take the pain girl… put more pressure on it… you’re not breaking my leg good. Break it!” the man says in video.

Police have identified the suspect as Anquando Johnson, 25.

“Break the neck… put your weight on it,” the man goes on to say as he flails his legs, kicking the female officer off him, and catching her once in the face with another kick.

When the officer tries to grab his legs again, the man forcefully boots the cop in the thigh sending her stumbling backward and tumbling onto the tracks.

The cop didn’t land near the third-rail and got right back up, the video shows.

Joaquin Santiago, who filmed the incident, told The Post the encounter started when the unhinged man spat in the face of one of the cops.

“Just let everyone know she’s fine,” he said of the officer.

“The officer could have easily been killed and as a result of this assault, the officer suffered a serious injury,” an NYPD spokesperson said.

“Any assault on a New York City Police Officer is an assault on society.”

Johnson was charged with felony assault on a police officer, plus reckless endangerment and theft of services. He was being held for evaluation at Harlem Hospital.
