NYPD Deputy Housing Chief Michael Harrington filed for retirement Thursday – joining a slew of police honchos heading for the exits amid a wide-ranging corruption probe.

Harrington, who was stripped of his gun and badge in early April in connection to the massive gifts-for-favors probe, submitted his papers Thursday at One Police Plaza.

Deputy Chief of Housing David Colon and James Grant, the commanding officer of the 19th Precinct, who also were transferred to desk duty, filed earlier this week.

The move comes days after Commissioner Bill Bratton announced in a radio interview that he expects arrests and disciplinary action against officers implicated in the probe – and that some “might choose to take retirement rather than deal with the public embarrassment of some of this becoming known in the news media and elsewhere.”
