Ram Singh Yadav is being interrogated by a team of senior officers to gain information about those who were behind the ambush.
While the police mentioned he is 20, his family has come out with his documents including his Adhaar card and mark sheet to claim that Prabhat was just 17.
ADG Prashant Kumar said that the slain gangster Vikas Dubey also looted the arms of the policemen after killing them.
The gangster, however, met a similar gruesome incident a week later on July 10 when he fell to STF bullets.
The SIT will submit its report by July 31 after looking into all the angles, studying all related documents and spot inspection in Kanpur, it said.
In the heartland’s badlands where crime writes the curriculum, caste is the syllabus and murder writes the chapters, the police write the exams.
The arrested persons have been identified as -- Om Prakash Pandey and Anil Pandey who helped to hide two wanted criminals -- Shashikant Pandey and Shivam Dubey. Further action is being taken.
While he has been handed over to a Uttar Pradesh police team after he admitted his crime, he will be brought to Kanpur by road.
Three persons close to Dubey have been arrested from Faridabad in a joint operation by Uttar Pradesh STF and local crime branch team, a senior official said.
The three suspensions are in addition to that of Chaubeypur police station in-charge Vinay Tiwari who was suspended on Saturday on suspicion of being the criminal’s informer.
Meanwhile, the cash reward for the information leading to the arrest of Vikas Dubey has been increased to Rs 2.5 lakh.
An FIR would also be lodged against the policemen and they would face further action if their involvement is proved during the course of inquiry.
Bithoor PS station officer Kaushalendra Pratap Singh said that Dubey's gang had been briefed about the imminent police raid and made preparations, even arranging the lighting.
As per the police sources, Daya Shankar Agnihotri alias Kallu, 42, a close aide of Dubey, sustained a bullet injury in his right left knee in the retaliatory firing by the police team.
Kanpur IG Mohit Agarwal on Saturday said that the pattern of attack was similar to that of Naxals.
