The Special Victims Squad of the New York Police Department is investigating a criminal complaint by man in his young twenties which alleges that X-Men director Bryan Singer sexually assaulted him in the Big Apple on March 23, 2013 as reported by BuzzFeed: "the 48-year-old Singer . . . has not been charged with a crime," and "whether he ever will be depends largely on what the investigation turns up." Earlier this week Michael Egan dropped his lawsuit which alleged Singer sexually abused him as an underage teen.
08/30/14 UPDATE: Apparently Singer will not be charged over the alleged incident "due to a lack of evidence" as reported by the New York Post.
