Manhattan’s district attorney dropped part of the criminal sexual assault case against Harvey Weinstein on Thursday after evidence emerged that cast doubt on the account one of his three accusers provided to the grand jury.

The development was announced in court Thursday with Weinstein looking on.

The tossed charge involves allegations made by one of the three accusers in the case, Lucia Evans, who was among the first women to publicly accuse Weinstein of sexual assault.

In an expose published in The New Yorker one year ago Wednesday, Evans accused Weinstein of forcing her to perform oral sex when they met alone in his office in 2004 to discuss her fledgling acting career. At the time, Evans was a 21-year-old college student.

Assistant District Attorney Joan Illuzzi-Orbon told the judge that prosecutors wouldn’t oppose dismissal of the count in the case involving Evans. She insisted the rest of the case, involving two other accusers, was strong.

“In short, your honor, we are moving full steam ahead,” she said.

Weinstein’s lawyer, Benjamin Brafman, told the judge he believed Evans had lied both to the grand jury and to The New Yorker about her encounter with Weinstein. He also said he believed a police detective had corruptly attempted to influence the case by keeping a witness from testifying about her misstatements.
