Taking suo motu cognisance of Soren's photograph in local newspapers today, the division bench of Chief Justice Prakash Tatia and Justice Jaya Roy asked the home secretary and the DGP to file their replies by July 16.

The vigilance bureau is investigating the case.
SP Balihar was killed along with four others in a suspected Maoist ambush of his police convoy in Damini forest in Jharkhand on Tuesday.
