The central bureau of investigation (CBI) probing Kunda triple murder case on Thursday moved an application in the court for the polygraph test of former minister Raghuraj Pratap Singh alias Raja Bhaiyya.
Special Magistrate of CBI court, Mirza Zeenat has fixed June 11 for the hearing of the petition.
CBI had grilled Raja Bhaiyya on May 15 and 16 in connection with murders of deputy superintendent of police Zia-ul Haque as well as gram pradhan Nanhe Yadav in Balipur village on March 2. Raja Bhaiyya denied his role in the murders.
Widow of slain DSP, Parveen Azad charged Raja Bhaiyya with hatching the conspiracy of her husband's murder.
Raja Bhaiyya resigned from the state cabinet on March 4 in the wake of the scandal.
Sources said, Raja Bhaiyya has shot off a letter to CBI that he has no role in the murder of the DSP and he was ready for the polygraph test. Taking cognizance of Raja Bhaiyya letter the CBI moved application for polygraph test.
The two brothers of Nanhe Yadav including Phoolchand Yadav, Pawan Yadav, son Babloo Yadav and private security guard Manjit Yadav were arrested on the charge of killing of the DSP.
Sources said CBI decided for the polygraph test of Raja Bhaiyya to ensure that no angle of his alleged involvement in the murder was left out.
Though CBI does not have any evidence which directly links Raja Bhaiya with the murder of the DSP, it wants to get a clear picture of his role, if any, in the case.
Earlier CBI court has rejected the application moved by CBI for the narco test of two cops Sarvesh Kumar Mishra and Manoj Kumar Shukla posted in Kunda.
