JAMAICA, N.Y. — Gruesome cell phone video shows an off-duty NYPD sergeant being brutally beaten outside a Queens diner early Sunday.

Sgt. Mohammed Deen was knocked to the ground and repeatedly punched and kicked by Hayden Holder, 29, according to the New York Post.

Sources said Deen had exchanged words with Holder earlier in the night at a nightclub.

Video shows Holder attempt to break the glass of the officer’s white BMW after beating him unconscious, as Deen’s wife sat locked inside, according to the report.

Holder was arrested and charged with felony assault. He admitted to the beating but said he did not know the victim was a cop.

Deen suffered critical injuries and is in a medically induced coma.
