NEW YORK — William Bratton says he will not remain commissioner of the New York Police Department past 2017.
The New York Times, which interviewed Bratton , says he also left open the possibility that he could leave even sooner.
The 68-year-old commissioner says he's "still young enough" to take on "additional challenges."
Bratton says he's already created a line of succession.
Bratton has been one of Mayor Bill de Blasio's most powerful defenders.
De Blasio spokesman Eric Phillips calls the news "very much expected" after Bratton's more than 45 years of service.
Phillips says that whenever Bratton decides to depart, he will leave behind "an unparalleled legacy of distinction."
In the meantime, Bratton and de Blasio will continue to work to reduce crime and improve community-police relations, Phillips said.
