An off-duty NYPD transit officer stabbed himself in the neck in Brooklyn on Friday, police sources said.

EMS responded to the officer’s home on Kimball Street in Marine Park at 2:40 a.m. and found him with stab wounds to the throat, authorities said.

He was rushed to Kings County Hospital Center and was listed in stable condition, cops said.

A woman outside the home declined comment.

“I really don’t want to talk right now,” she said.

The officer was not identified by police.
