NEW DELHI (TIP): The CBI today conducted liedetection test on former UP Cabinet Minister Raghuraj Pratap Singh, alias Raja Bhaiya, on charges of his alleged involvement in the murder of DSP Zia-ul-Haque. He reached CBI headquarters for the test and remained there for a few hours. When he came out, he was satisfied, sources said. A few days back, he had appeared before a special CBI court in Lucknow and agreed to undergo the test.

According to the CBI, Raja Bhaiya was a suspect in the murder of the DSP from the very beginning of the investigation into the case. The lie-detection test may provide evidence against him, the sources said. Haq was shot dead in Balipur village in Kunda area of Pratapgarh district where he had gone to probe the murder of village head Nanhe Yadav. The deceased police officer’s wife Parveen Azad had accused Raja Bhaiya of hatching a conspiracy after which he had to resign from the Cabinet on March 4.
