NEW YORK (CBSNewYork) — Another high-ranking police officer was disciplined Wednesday in connection with the ongoing federal probe into corruption at the NYPD.

Meanwhile, a detective who already had been suspended has now been fired.

Inspector Peter DeBlasio, who is not related to Mayor Bill de Blasio, was placed on modified duty Wednesday after being questioned as part of the investigation, police told CBS2.

It was not known specifically why Inspector DeBlasio specifically being looked at, and why he was disciplined.

Inspector DeBlasio is the former commander of the 66th Precinct in Borough Park, Brooklyn and is currently assigned to the Patrol Borough Brooklyn South.

NYPD Captains Endowment Union President Roy T. Richter released a statement following the disciplinary action.

“The inspector has cooperated fully and answered questions presented to him by federal investigators at his home in an early morning unscheduled interview – weeks ago,” Richter said in the statement. “Today’s action by the NYPD is unexpected.”

Meanwhile, police said Detective Michael Milici, who was suspended on March 31, has now been fired.

Police last month told CBS2 that Milici, of the 66th Precinct in Brooklyn, tried to try to retire quietly from the NYPD. His file was flagged by Internal Affairs because it is prohibited for anyone to retire as a way of dodging departmental charges.

The licensing division of the NYPD is at the center of another of the investigations.

The NYPD probe has centered on two businessmen who have ties to de Blasio’s campaign. Jeremy Reichberg and Jona Rechnitz both served on de Blasio’s inaugural committee and either donated or raised money for him.

So far, at least eight other police officials, including four deputy chiefs, have been transferred or stripped of their guns and badges as internal affairs detectives and FBI agents examine whether officers accepted gifts and trips from businessmen in exchange for police escorts, special parking privileges and other favors.

The probe has also involved an investigation of payoffs for gun licenses. Alex “Shaya” Lichtenstein of Brooklyn has been charged with bribing police to give him gun permits without doing background checks or providing justification for owning a gun.

The investigation has also focused on fundraising efforts by Mayor de Blasio and his campaign team.
