The New York Police Department has closed three sexual assault investigations involving chefMario Batali, according to theNew York Times.

A NYPD official told theNYT, “the charges in two of the case were beyond the New York State statute of limitations, which was lifted in 2006, but not made retroactive,” while the third allegation was dropped due to lack of criminal evidence.

The NYPD declined to comment to PEOPLE on the specifics of any particular investigation.

The chef has admitted acting inappropriately but has denied ever sexually assaulted anyone.

One of the womenaccused Batali of drugging and sexually assaulting herwhile she was unconscious in 2005.
