Although there have been no current credible threats against his life, Ray Kelly has attempted to keep his police security detail 14 months after he retired as NYPD commissioner.

The NYPD ended his 11-person detail, which included two sergeants and a lieutenant, on Feb. 28. An NYPD official who asked for anonymity to speak freely about the issue said, "There were no known current credible threats."

Another NYPD official who also asked for anonymity said the department had planned to end Kelly's detail last summer but extended it through the end of year after the death of Eric Garner in Staten Island.

"There was a lot of anger out there. [NYPD Commissioner Bill] Bratton was smeared with red paint," said the official. "Then, there was the assassination of the two officers."

The department had provided Kelly with the detail when he retired in January 2014, as Bill de Blasio became mayor. The cost to taxpayers for the 14 months was more than $1 million.

After learning that the NYPD planned to discontinue the detail, Kelly scrambled to find a way to continue it. Two sources, one in the NYPD, the other outside it, said Kelly initially pointed to former Manhattan D.A. Robert Morgenthau -- for whom Kelly provided a police detail as a courtesy when Morgenthau retired in 2009 at age 90. It continues to this day.

The two sources said Kelly then contacted Gov. Andrew Cuomo, who last year appointed Kelly as an unpaid special adviser of a new college dedicated to emergency preparedness and homeland security. The NYPD source said Kelly sought Cuomo's intercession with City Hall.

Dani Lever, a Cuomo spokeswoman, said the state is not providing Kelly with a police detail and denied that he requested one.

As commissioner for 12 years, Kelly will be remembered largely for his aggressive use of stop and frisk, which a federal judge ruled was racially discriminatory, and his creation of an international NYPD Intelligence Division in the wake of 9/11.

Kelly reportedly now earns close to $1 million a year as an executive with commercial real estate broker Cushman & Wakefield.

Neither Kelly nor company president Ed Forst returned a call. As of last week, Kelly had a private security detail. Whether he or Cushman & Wakefield is paying for it is unknown.
