The NYPD detective who went viral after twerking in a thong and skimpy bra in a rap video will no longer investigate active cases with the Special Victims Division, which investigates sex crimes, police sources told the New York Post.

Melissa Mercado’s behavior was under review, an NYPD spokeswoman said. The department didn’t immediately answer when asked if the seven-year NYPD veteran had broken any specific rules when she appeared in the “Doin That” video by Hempstead rapper S-Quire.

Pitch Perfect, who directed the music video, told TMZ Friday that he and the rapper hired Mercado from a casting agency and were unaware of her day job.

The video was posted by the online site WorldStarHipHop and can be viewed here.

She was not named in the clip — which quickly made the rounds among the rank and file — and she wasn’t wearing anything that would identify her as an NYPD officer.

It was particularly disturbing for a sex crimes investigator to make a video that’s degrading to women, retired NYPD Special Victims Division Chief Michael Osgood told the Post.

Mercado did not return calls from The Post.
