One of the top overtime earners in disgraced ex-NYPD Chief Jefferey Maddrey’s office is talking to federal investigators as they probe sex-for-overtime allegations uncovered by The Post, law enforcement sources said.

Law enforcement officers on Thursday searched the home of former New York City Police Department Chief of Department Jeffrey Maddrey, who resigned late last month after being accused of demanding sex from a subordinate in exchange for opportunities to earn extra pay.

Former NYPD Chief of Department Jeffrey Maddrey is now formally suspended, and federal agents searched his home Thursday.
