Special Judge Virender Kumar Goyal granted the relief to IB Assistant Director Kameshwar, Delhi Police inspector Banay Singh Meena and two alleged middlemen -- Rajan Kumar and Arun Tiwari -- on a personal bond of Rs 50,000 each.

In their bail application, the accused had claimed that they were not required for the probe since the CBI had already filed the charge sheet.
The CBI had on October 7 filed a charge sheet in the case against the four. The case was registered on August 9 against them for allege criminal conspiracy, illegal gratification and commission of offence of abetment by public servant.
"During course of investigation, the CBI had intercepted the accused persons and recovered the alleged gratification amount of Rs 10 lakh (approx) from the private persons," the agency had alleged and added that it had carried out searches at several premises of the accused in Delhi.
