The murder of an IndiGo Airlines executive in Bihar's Patna has triggered a political backlash for Chief Minister Nitish Kumar, with the opposition demanding his resignation and even leaders of his ally BJP criticizing him openly. Rupesh Kumar Singh, 44, a manager with the private airline, was shot dead last evening outside the gates of his home, barely two km from the Chief Minister's residence. He was waiting in his SUV for the gates to open when two men riding a bike opened fire at him.
