The Supreme Court on Monday pulled up the Karnataka police for not doing anything to unearth the murder of the rationalist M.M. Kalburgi outside his home in Dharwad on August 30, 2015.

"What have you done so far? You are just fooling around," said the bench of Justice Fali Nariman and Justice Navin Sinha asking the state police to spell out how much time it would require to complete the investigation.
