Another top NYPD commander caught up in the gifts for favors corruption scandal has filed for retirement, police sources said Friday.
Deputy Chief Michael Harrington is the third higher-up to call it quits this week.
He was second in command for the Housing Bureau until he was transferred and placed on modified duty, stripped of his gun and shield, in early April.
The 30-year veteran filed his papers on Thursday, starting the clock on the 30 days that the department has to file departmental charges against him.
Roy Richter, head of the Captains Endowment Association, the union representing those with the rank of captain and above, had no comment.
Police Commissioner Bill Bratton has said he expects the investigation will result in federal indictments.
Police sources have said it appeared unlikely Harrington would be indicted, though he could face departmental charges.
Harrington is friends with ex-Chief of Department Philip Banks, for whom he once worked.
Banks, who is also linked to the probe, is friends with two businessmen at the heart of the probe.
The businessman, Jona Rechnitz and Jeremy Reichberg, were on the inauguration committee for Mayor de Blasio, whose fund-raising activities are also under investigation.
Earlier this week, Deputy Chief David Colon and Deputy Inspector James Grant filed for retirement.
Colon, who has had been transferred out of the Housing Bureau, is friends with Hamlet Peralta, a restaurateur recently indicted for running a Ponzi scheme.
And Grant, who used to run the 19th Precinct on the Upper East Side before he was modified and transferred, is suspected of taking gifts in exchange for vehicular escorts.
