BSP chief Mayawati on Sunday said the killing of gangster-turned-politician Atiq Ahmad and his brother Ashraf in police custody in Prayagraj raises serious questions over the style of functioning of the Uttar Pradesh government. It would be better if the Supreme Court takes cognisance of this "extremely serious and worrisome" incident, which is being discussed across the country, the former Uttar Pradesh chief minister said. In a series of tweets, she said, "Now, instead of 'rule of law by law' in Uttar Pradesh, how appropriate is it that it becomes 'encounter Pradesh'? Something to think about."
