Friday’s hearing came after Krishna’s counsel R K Anand filed an application requesting the court for documents such as the postmortem report, a copy of the FIR, and reports of tests conducted on Krishna.

Anand also argued that the court had power to release an accused if no evidence is found against him. He contended CBI had kept Krishna under “illegal detention”.

But prosecution counsel R K Saini told the court that the accused cannot be released as investigations are still on.

Rajkumar’s counsel Sanjay Tyagi had submitted an application alleging that CBI had tortured his client physically and mentally. The application quotes Raj Kumar as saying that he does not “know Krishna, but CBI officials have threatened to kill” his family if he “does not become (a) prosecution witness”.

The application was filed his lawyer.

“It is a blatant violation of my client’s rights if the CBI keeps him in custody without evidence against him,” Tyagi said.

The application filed on behalf of Raj Kumar also says: “They (CBI investigators) asked me to tell the court that Krishna had killed the two (Arushi and Hemraj)… Talwar had called me on May 16 and asked me to wash the blood-soaked clothes and asked to serve water to guests.”

The investigating agency had earlier given a clean chit to Arushi’s father Dr Rajesh Talwar, a prime suspect for Noida police after their initial suspect — household help Hemraj — was found dead a day after Arushi’s body was found.

The CBI had also made it clear that no corroborative evidence had been found against the three accused helps: Raj Kumar, Krishna, and Vijay Mandal.
