He has also been charged with section 341 (wrongful restraint) and section 342 (wrongful confinement) of the Indian Penal Code (IPC) last week.
The police have already recorded the statements of the victim, three witnesses and Tehelka's former managing editor Shoma Chaudhury sworn before a judicial magistrate even as sources said that the investigators had been unable to break Tejpal and extract a confession from him.
Tejpal is alleged to have insisted to his investigators during interrogation that the sexual encounter with the victim was consensual.
