Last week, Detective Nicholas DiGaudio was accused of coaching a witness, causing one of the six felony charges against Weinstein to be thrown out.

Weinstein has pleaded not guilty to the charges. His attorney, Benjamin Brafman, has said his client maintains “he has never engaged in non-consensual sexual behavior with anyone.”

The District Attorney’s Office on Tuesday said DiGaudio told an accuser to delete cell phone messages prior to turning her phones over to authorities. This action could impact three of the five counts Weinstein is currently facing: predatory sexual assault and rape in the first and third degrees.

DiGaudio is now the subject of an internal NYPD investigation and has been removed from the Weinstein case. He has not responded to CNN’s request for comment.
