A young woman died in NYPD custody at a Bronx precinct station house Saturday after police officers’ attempts to revive her failed, cops said.

The 18-year-old became unconscious while in custody at the 41 Precinct station on Longwood Ave. in Hunts Point around 12:30 a.m., cops said.

Police called for an ambulance and attempted to revive her, officials said.

“Multiple officers performed CPR while awaiting EMS response,” cops said in an official release about the woman’s death.

EMS rushed the woman to Lincoln Hospital, but she couldn’t be saved, police said.

Her identity wasn’t immediately released.

Police declined to say why the woman was in custody and cited an ongoing invesigation being done by the NYPD’s Force Invesigation Division.
