NYPD Chief of Department Rodney Harrison will be nominated to be Suffolk County’s next police commissioner, a spokesperson for Suffolk Executive Steve Bellone tells News 12.

A formal announcement is expected to be made by Bellone Tuesday at 11:30 a.m. in Hauppauge.

Earlier this year, Harrison, the New York Police Department's highest-ranking uniformed officer, announced he was retiring on Dec. 30 after become the first person ever to rise from cadet to chief of the nation's largest police department.

During his 30-year career, Harrison served as the department's first African American chief of detectives, was shot while working undercover investigating drug crimes in the 1990s, held assignments in each of the city's five boroughs and had the distinction of being the official in charge of monitoring wind speeds to decide whether the giant balloons of the Macy’s Thanksgiving Day Parade could fly in various years.

In recent years, he was instrumental in implementing the department’s “neighborhood policing” strategy, which pushes officers out of their patrol cars and onto the streets so they can build bonds with residents.
