The city’s Civilian Complaint Review Board moved Wednesday to substantiate an excessive-force claim against the “chokehold” cop involved in the 2014 death of Eric Garner on Staten ­Island, a source said.

The board decided to authenticate the claim against NYPD Officer Daniel Pantaleo, even as federal prosecutors present evidence to a grand jury, according to the source.

The move by the CCRB, made during a closed session with no public notice, will send the allegation through a departmental process that could include an ­administrative NYPD trial and disciplinary action.

The former head of the CCRB Richard Emery said in 2015 that the US attorney’s office in the Eastern District of New York had asked them to hold their inquiry. Emery decided to obey that decision “pending a final resolution” by the feds.

A spokesman said, the “CCRB continues to honor the DOJ (Department of Justice) request.” But the agency wouldn’t discuss or even acknowledge the decision​.

Pantaleo’s attempt to restrain Garner, suspected of illegally selling cigarettes, led to Garner’s death in an incident caught on videotape.

The cop has not been charged with a crime.

A spokesperson for the CCRB declined to comment Wednesday night.
