"The investigations in the case are almost in the final stage," the senior crime branch official said.
"We are waiting for the forensic report of the gadgets seized from Tejpal. The charge sheet would be filed by this month end," he said.
The crime branch during its investigation had seized gadgets like mobile, laptop of Tejpal which were used to communicate, after the alleged offence took place.
Tejpal, 50, was arrested on November 30 in Goa after his anticipatory bail plea was rejected by a district and sessions court.
A former junior woman journalist of the Tehelka magazine had alleged that Tejpal had sexually assaulted her inside the lift of a five-star hotel during an event in Goa last year.
The investigating officer has already recorded several statements, including that of former Tehelka managing editor Shoma Chaudhury and Tejpal's daughter, along with the deposition of the victim in connection with the case.
"The statements of the five-star hotel staff who were on duty during the time when the incident allegedly happened are also recorded. The recordings completed last week itself," the official said.
The crime branch officials expect to file a "water tight" case against Tejpal, who is currently lodged in Sada sub jail after the local court rejected his bail and continued with the judicial custody.
