The 15-year-old teen initially spoke to officers then was interviewed by a detective who determined nothing had happened to him.
The change left open the possibility that the teen could be charged for fabricating the story, Hercules police Detective Connie Van Putten said.
The student, who is biologically female but identifies as male, initially told officers he was leaving a boy's bathroom Monday morning at Hercules Middle/High School when the assailants pushed him inside a large stall and attacked him
But as the investigation continued, officers could not substantiate the facts of his statement, and he lacked any physical injuries to his head, face and hands, police said.
The student finally admitted he had made up the story, Van Putten said.
She would not speculate on why he had lied.
