The former Minister of Uttar Pradesh, Raghuraj Pratap Singh alias Raja Bhaiya, has given his consent to undergo a polygraph test in connection with the Kunda DSP Zia-ul-Haque murder case, before the Special CBI court here on Tuesday. The court reserved its order.

Earlier this month, the CBI moved an application in the court, seeking permission for a lie-detector test on Mr. Singh. In the FIR filed by the police officer’s wife, Parveen Azad, the Kunda MLA has been charged with criminal conspiracy.

Mr. Singh told reporters that he would assist the CBI. An enquiry should also be conducted to ascertain why his name was dragged into the case. He had always maintained that he would assist the investigating agency, he said.

Mr. Singh had resigned in the aftermath of the DSP’s murder at Balipur village in the Kunda Assembly constituency in Pratapgarh district on March 2.

He was grilled by the CBI on May 15 and 16. Later, the investigating agency filed a charge sheet in the Special CBI court against 14 persons. Mr. Singh’s name was not in the charge sheet. However, next day the CBI moved an application, seeking the court’s permission to conduct a polygraph test on him.
