Ratan Suryawanshi recorded his statement before additional district judge Jitendra Kumar Sharma, April 01, according to sources in prosecution.
Suryawanshi, who teaches English at a government college here, had helped police in overcoming the language barrier and subsequent registration of FIR after the Swiss couple approached them following the incident on March 15.
The trial in the case began on March 30. The court also completed recording of the statement of prosecution witness Bhagwat Gurjar, even though the Swiss couple could not participate in the court proceedings as they have reportedly left the country.
The court posted the next hearing for tomorrow which will take place in a fast-track manner, the sources said.
The 39-year-old Swiss tourist was allegedly gangraped on March 15 when she was camping along with her male companion in a tent here.
Following the incident, police arrested Baba, Bhuthda, Gaza alias Brajesh, Vishnu Kanjar and Nitin Kanjar as accused.
Except Nitin and Vishnu Kanjar, who were charged with assault and robbery, all others have been charged with gangrape.
The incident had triggered outrage and even rocked the state Assembly following which it was adjourned sine die.
