In a scathing counter to the Delhi Chief Minister's demand for CBI probe into the hooch tragedy, Punjab Chief Minister Amarinder Singh, here on Sunday, told Arvind Kejriwal to mind his own business and not to exploit the tragic event for reviving his defunct Aam Aadmi Party (AAP) in the state. Singh ticked off Kejriwal over the latter's Twitter remark that the case should be handed over to the Central Bureau of Investigation (CBI). "So many people have died and all you are interested in is making a political gain from it. Don't you have any shame?" he asked Kejriwal and told him to concentrate on maintaining law and order in his own state, which was notorious for the brazen manner in which criminals and gangs were roaming the streets.
