He will be the 44th leader of the NYPD.

Shea is a Queens native who has been with the force since 1991. He says he plans to take neighborhood policing to the next level.

“I’m looking forward to working with everyone who lives, works, and visits here to make New York City even safer,” he said.

Shea is replacing outgoing Commissioner James O’Neill who spent three years on the job.

O’Neill, 61, retired from the NYPD to take a job as Visa’s senior vice president and global head of physical security.

De Blasio has credited Shea with building strategies that drove crime to record lows.

When he announced Shea’s appointment, the mayor called him “one of the best-prepared incoming police commissioners this city has ever seen.”

The new commissioner has already been met with criticism, however. Some New Yorkers questioned why de Blasio passed over Deputy Commissioner Benjamin Tucker for the top job.
