Amid a raging controversy over the suspension of IAS officer Durga Shakti Nagpal, Congress President Sonia Gandhi has written to Prime Minister Manmohan Singh, saying the bureaucrat must not be "unfairly treated". The young officer was shunted out by the Uttar Pradesh government for ordering the demolition of a wall that was meant to house a mosque. But supporters of the 28-year-old officer, who was the Sub-Divisional Magistrate of Gautam Budh Nagar, say that she was punished for taking on the powerful sand mining mafia in the state.
