Kristen Cohen was the first to publicly speak about her alleged experience with Westwick, when she claimed she had been raped by the actor in 2014.
Her allegations then prompted a second claim from Wynn, who alleged that a "similar" ordeal happened to her when she visited Westwick's home with her boyfriend at the time, Mark Salling, and then another from Eck, who claimed the actor had groped her breasts when she and her ex-boyfriend visited him at a villa in West Hollywood.
However, the 30-year-old actor - who was fired from BBC drama Ordeal by Innocence in the wake of the claims - took to social media to slam the allegations against him as "provably untrue", and insisted he would never do anything so "vile and horrific".
He wrote in the now-deleted message: "It is disheartening and sad to me that as a result of two unverified and provably untrue social media claims, there are some in this environment who could ever conclude I have had anything to do with such vile and horrific conduct.
"I have absolutely not, and am cooperating with the authorities so that they can clear my name as soon as possible.(sic)"
