NEW YORK (AP) — The police commander who led the effort to arrest Harvey Weinstein has been removed as the chief of New York City's special victims division, part of a shake-up that was months in the making after a city watchdog found the unit was stretched too thin to properly investigate sexual assault cases.

Deputy Chief Michael Osgood, whose final weeks were marred by allegations that a top detective had compromised the Weinstein case, will take on a leadership role in Staten Island. Deputy Chief Judith Harrison takes over the special victims division, the police department announced Friday.

"If we can get better, we will get better," Harrison said.

Police Commissioner James O'Neill signaled changes were coming back in April when he pledged a "top-to-bottom scrub" of the unit after a report by the city's Department of Investigation showed that the sex crimes caseload had ballooned by 65 percent since 2009, but staffing levels were nearly unchanged.

Department memos included in the report showed that Osgood had been asking for more staff for at least four years. He had also requested additional training for detectives and recommended starting a cold case squad.

The police department review was just wrapping up last month when evidence surfaced that Det. Nicholas DiGaudio, whom Osgood worked closely with on the Weinstein case, had coached a witness and told one of the movie producer's accusers to delete material from her cellphone. Weinstein's lawyers said last week that they want to question Osgood in court about DiGaudio's conduct.

DiGaudio's alleged coaching led prosecutors to drop one of Weinstein's charges. Afterward, police said he was no longer involved in the case. His union has said he "was simply trying to get to the truth" and wasn't trying to influence the investigation.

Weinstein denies all allegations of nonconsensual sex.

Chief of Detectives Dermot Shea, who led the police review of the special victims division, thanked Osgood for his "dedication and tremendous contributions" in his eight years in charge of the unit.

The head of Osgood's union said he was "not just the expert, but the innovative creator of modern day investigative techniques and policing of sex crimes offenses."

Roy Richter, the president of the Captains Endowment Association, said Harrison is a talented commander and that he is "confident she will meet this challenge as she has excelled with others in the past."

Harrison, a 21-year member of the NYPD, has been a precinct commander in Queens and led patrol units in the neighborhoods near LaGuardia Airport. She was promoted in July to deputy chief and was assigned to the detective bureau, which oversees the special victims division.

As she takes over, the division is being streamlined into two squads — one focusing on crimes against adults and the other on child abuse. The hate crimes unit, which had been a part of the special victims division, is being moved to the special investigations division, which includes the computer crimes and major case squads.

The Department of Investigation report, issued in late March, found there were just 67 special victims detectives for a caseload of 5,661 suspected attacks last year, leaving the bulk of assault cases to precinct-level detectives who had less training and experience dealing with victims. As a result, police prioritized stranger rapes while sexual assaults committed by acquaintances received less attention.

Since then, the NYPD has transferred about three dozen investigators into the special victims division, freed up about a dozen more to handle cases and, as of July, is requiring that unit detectives investigate all felony sex crimes.

The added staffing has dropped the average caseload from 76.5 per detective at the end of 2017 to 63.7, and it's projected to fall further next year even if reports of sexual assaults continue to trend upward, the department said.

The department, criticized in the report for re-traumatizing victims and jeopardizing prosecutions, accelerated a program to train all special-victims investigators in interview techniques that are meant to be more compassionate and understanding than typical questioning. It's also heeding a recommendation in the report to repair police facilities to make victims more comfortable.

"We are deeply committed to doing everything and anything necessary to ensure survivors feel the safety and support needed to come forward, bravely share their experiences, and help the NYPD bring to justice those who have committed these horrific crimes," Shea said.
