A CBI probe has been ordered after controversial former Uttar Pradesh minister Raghuraj Pratap Singh alias 'Raja Bhaiya' was booked for alleged conspiracy in the killing of DSP Zia-ul-Haq in mob violence in Pratapgarh district on Saturday (March 2). But, questions are now being raised about whether this is mere eye wash, and an attempt to buy time and why has Raja bhaiya still not been arrested?
