The family of a 17-year-old who was allegedly knocked unconscious by a New York police officer released a video of the incident, New York Magazine’s Daily Intelligencer reported on Wednesday.

The cellphone video reportedly showed teen Marcel Hamer on the ground after being stopped by an NYPD officer.

His lawyers told the blog that a plainclothes NYPD officer suspected Hamer of smoking marijuana, but the lawyers noted that their client was only charged with disorderly conduct.

In the video, according to the Daily Intelligencer, Hamer tried to explain that he wasn’t smoking marijuana.

“Mister, it was just a cigarette, sir,” Hamer reportedly said.

According to The Daily Intelligencer, Hamer was then struck and appeared to have been knocked unconscious. The officer can then reportedly be heard talking.

“Do you wanna get fucked up?” the officer said. “Yeah, get it on film.”

The incident occurred on June 4 and led to an investigation by the NYPD’s Internal Affairs Bureau, according to The Brooklyn Paper. Hamer’s family told the paper that he suffered memory loss, dizziness and headaches after the incident.
