New York City Police Commissioner William Bratton speaks during a news conference at the police headquarters in New York January 12, 2015. Commissioner Bratton said on Monday that police were starting to "reengage" after a slowdown following the killings of two police officers, with arrests down 38 percent last week compared to the same period a year earlier.
New York Police Department Commissioner Bill Bratton will announce his resignation on Tuesday, multiple outlets reported.
Bratton will be replaced by the current Chief of Department James O'Neill, the Wall Street Journal reported, citing unnamed city officials.
Mayor Bill de Blasio is scheduled to announce the move at a joint news conference with Bratton at noon, according to the Journal.
Bratton will reportedly remain in his post until September - as his replacement transitions into the job - before he returns to the private sector.
