According to reports, the CBI has not found any evidence to prove Raja Bhaiya guilty during its preliminary investigation.
"Raja Bhaiya has been summoned at the CBI camp office to clear some doubts. We sent the notice to his houses in Kunda and Lucknow late Thursday," said a CBI official on Friday.
Pertinently, the probe agency has named Raja Bhaiya and four others in one of its four FIRs.
Earlier on Mar 26, the family of slain village head of Uttar Pradesh's Balipur village Nanhe Yadav alleged that Raja Bhaiya had threatened them.
Nanhe Yadav, his brother and DSP Zia-ul-Haque were killed at Pratapgarh district in Uttar Pradesh on Mar 2.
"Raja Bhaiya called us and said if we told the CBI anything about him or his family, we will be killed. He also threatened our father and the women in our family saying that if they opened their mouths, the others won't be spared too. We want security," Nanhe Yadav's brother Pawan Kumar Yadav told CNN-IBN.
"If we are killed, Raja Bhaiya will be responsible," Pawan Kumar Yadav said.
Raja Bhaiya had resigned after he was booked in the killing of the DSP.
Two of Raja Bhaiya's alleged aides were arrested in the case based on a complaint filed by Zia-ul-Haque's wife who had accused the politician and his men of killing her husband.
