Los Angeles County prosecutors have decided not to file rape charges against actor Ed Westwick, citing insufficient evidence.

Westwick, best known for his role on “Gossip Girl,” was accused in November of raping two women and sexually assaulting a third in 2014. Actress Kristina Cohen made the first allegation in a post on Facebook, writing that Westwick held her down and raped her at his home in West L.A. Two more women came forward with their own accounts, actress Aurelie Wynn and Rachel Eck.

In a memo on Friday, prosecutors said they did not have enough evidence to pursue charges. According to the memo, two of the women provided witnesses to help corroborate their accounts, including some who were outside the room where the alleged incident took place.

“Those witnesses were not able to provide information that would enable the prosecution to prove either incident beyond a reasonable doubt,” prosecutors wrote.
