William J. Bratton will step down from his position as the commissioner of the New York Police Department next month to take a job in the private sector, according to a New York Times report. This move will mark the end of Bratton’s 45-year career in public life.

He will be replaced by the NY Police Department’s top uniformed officer, Chief James O’Neill, a veteran New York commander who became a police officer in 1983, the report says.

New York City Mayor Bill de Blasio appointed Commissioner Bratton shortly after the mayoral election in 2013. Bratton had previously served as New York City’s police commissioner in the mid-1990s under Mayor Giuliani. Bratton also served as the Chief of the Los Angeles Police Department from 2002 to 2009.
