A spokesperson for the NYPD has confirmed hat the criminal investigation into sexual assault allegations against Hollywood producer Harvey Weinstein is moving forward.

Chief detective Robery Boyce said: "There has been no determination on where its going to go, or what timeline has been done as to when it's going to go to a grand jury."

Detective Boyce also said he has sent detectives to Los Angeles on the multi-front case.

"I have two detectives in LA right now. I have sent them to Paris. I have sent them pretty much around the world ... More women coming out: its a good thing. We see a decided increase in the people coming forward and having faith," he stressed.

More than 100 women have come forward since October to accuse Weinstein of bullying and degrading behavior over the past 40 years, from intimidation to rape.

But many of the allegations could not be investigated criminally because of statutes of limitations. 

A few woman actually have filed criminal charges. New York-based actress Paz de la Huerta alleges that Weinstein raped her at her Manhattan home in 2010, while another woman in Los Angeles and another in London also made similar claims.
