Armie Hammer's sexual assault case has been reviewed by Los Angeles police. It's been determined the actor won't face charges, the LA District Attorney’s Office told CNN on Wednesday.

“Sexual assault cases are often difficult to prove, which is why we assign our most experienced prosecutors to review them. In this case, those prosecutors conducted an extremely thorough review, but determined that at this time, there is insufficient evidence to charge Mr. Hammer with a crime,” Tiffiny Blacknell, Director of the Bureau of Communications said.

“As prosecutors, we have an ethical responsibility to only charge cases that we can prove beyond a reasonable doubt. We know that it is hard for women to report sexual assault,” Blacknell continued. “Even when we cannot move forward with a prosecution, our victim service representatives will be available to those who seek our victim support services. Due to the complexity of the relationship and inability to prove a non-consensual, forcible sexual encounter we are unable to prove the case beyond a reasonable doubt.”

Hammer's alleged victim Effie spoke out after the decision, “I am disappointed with the LA County District Attorney’s decision not to prosecute Armie Hammer. I felt a duty to speak out and file a report in order to try to hold Armie accountable for all the harm and trauma he has caused me and in order to protect other women from experiencing similar abuse.”

Hammer took to Instagram to share his point of view: “I am very grateful to the District Attorney for conducting a thorough investigation and coming to the conclusion that I have stood by this entire time, that no crime was committed. I look forward to beginning what will be a long, difficult process of putting my life back together now that my name is cleared.”
