Tamil Nadu government has issued a lookout notice against Union Chemicals and Fertilisers Minister M.K. Alagiri's son Durai Dayanidhi Alagiri for his alleged involvement in the multi-crore granite mining scam.

But the state opposed a bunch of petitions in the Madras High Court seeking a CBI probe into the illegal granite quarrying in Madurai district. Advocate General Navaneetha Krishnan told the bench on Friday the government would nab the culprits behind the illegal quarrying and was not protecting anybody.
