BROOKLYN - The city's highest ranking police officer is retiring after more than 40 years of service.

Chief Joseph Esposito began his career at the 77th Precinct in Crown Heights, and has been chief for more than 12 years, which is longer than any of his predecessors. During that time, he's credited with reducing crime and introducing new policing strategies.

Philip Banks III will take Esposito's place, becoming the 37th person to hold the post. The NYPD veteran also has ties to Brooklyn, serving as an executive officer in the borough during his 26-year career.
