Back in 1992, a police investigation was launched after Dylan Farrow accused her adoptive father Woody Allen of sexually abusing her.
She was supported by her adoptive mother Mia Farrow, who insisted that her daughter was speaking the truth.
But Woody Allen has always maintained his innocence and no charges were ever brought against him.
In the blog, Moses Farrow starts off: "I’m a very private person and not at all interested in public attention. But, given the incredibly inaccurate and misleading attacks on my father, Woody Allen, I feel that I can no longer stay silent as he continues to be condemned for a crime he did not commit.
"I was present for everything that transpired in our house before, during, and after the alleged event. Now that the public hysteria of earlier this year has died down a little and I have some hope that the truth can get a fair hearing, I want to share my story."
Disputing his sister's claims that she was sexually abused, Moses writes: "Dylan was alone with Woody in his apartment countless times over the years without a hint of impropriety, yet some would have you believe that at the age of 56, he suddenly decided to become a child molester in a house full of hostile people ordered to watch him like a hawk.”
But Dylan Farrow has now dismissed her brother's blog as "an attempt to deflect from a credible allegation made by an adult woman, by trying to impugn my mother who has only ever been supportive of me and my siblings.”
“It’s easily disproven, contradicts years of his own statements, is beyond hurtful to me personally, and is part of a larger effort to discredit and distract from my assault,” she told People magazine. “My brother is a troubled person. I’m so sorry he’s doing this.”

One of the things that I have found most disturbing about sharing my story is how many strangers feel compelled to tell me what I “really” experienced and what my family is “really” like.

To presume I invented this story & convinced myself of it is no less insulting than calling me a liar. I’ve consistently stated the truth for 25 years, I won’t stop now. It’s Stephens’ right to doubt me if he so chooses but his incredulity doesn’t change what happened that day./2
