MLB investigator looking into A-Rod has shady past

The investigator accused in Alex Rodriguez’s scathing lawsuit against Major League Baseball of handing over a bag of cash in exchange for client records stolen from a Florida PED clinic was himself probed for shady tactics while he was a Deputy Inspector for the NYPD in the 1990s, The Post has learned.

Dan Mullin, senior VP of investigations for MLB, was in charge of one of Manhattan District Attorney Robert Morgenthau’s detective squads, when he was reportedly investigated on allegations he held a hooker against her will for seven hours.

Mullin, 55, had hauled $400-an-hour escort Stacey Miller in for questioning in 1995 about connections between her place of work, the Crown Club, and organized crime, Newsday then reported.

He got the tip about Miller from a high-ranking cop, Deputy Inspector Charles Luisi. Luisi was also being probed by Internal Affairs — for taking gifts from a top gun dealer named Michael Zerin, who just happened to be in the middle of a nasty divorce from the escort Miller.

Miller filed false imprisonment charges against Mullin.

“There was a concerted effort between the NYPD and the DA’s police squad to silence her,” Miller’s divorce attorney Nina Epstein told The Post on Monday.

Mullin was transferred out of the DA’s office to a borough command.

Mullin insisted to The Post that the move was a promotion. He acknowledged that detectives under his command were investigated for the incident, but he claimed he was never the target of the probe and his department was never found guilty of any wrongdoing.

Meanwhile, MLB on Monday told A-Rod he was barking up the wrong tree.

Major League Baseball filed a motion to get Rodriguez’s Manhattan lawsuit accusing the league and Commissioner Bud Selig of being on a “witch hunt” to ruin his faded career moved from state to federal court. The case was re-assigned to Manhattan federal Judge Lorna Schoefield.

The league’s motion argued the case belongs in federal court — where judges are historically tougher — because Rodriguez is bound by the collective bargaining agreement between MLB and its Players Association and that disputes under the agreement are covered by the federal Labor Management Relations Act.

“Mr. Rodriguez’s claims against MLB and Commissioner Selig arise from their tortious conduct, separate and apart from the issues being decided in the arbitration process,” Rodriguez’s lawyer Joe Tacopina said.

“MLB knows that these state law claims properly belong where they were filed, in the New York State Court.”

Tacopina, however, added that “our facts” in the case “will stand scrutiny in any forum.”

Neither Luisi nor his lawyer immediately returned calls for comment.
