The person accused of leaking police records of the officer involved in Eric Garner's death is no longer on the job.
Earlier in the week, the liberal news site Think Progress published Officer Daniel Pantaleo's disciplinary records.
The Civilian Complaint Review Board, the agency that investigates police misconduct, says it identified the employee who leaked the information.
It says they were a "very junior" staff member who ultimately resigned, and worked there for less than a year.
The leaked police records show Pantaleo had more than a dozen past allegations against him.
It comes as civil rights lawyers sue the city over access to all police disciplinary records.
All the allegations against Pantaleo happened before he put Garner in a deadly chokehold in 2014.
A grand jury declined to indict him, but a departmental trial is pending.
