Priyanka Gandhi Vadra, arrested in the early hours of Monday on her way to Lakhimpur Kheri where eight protesters were killed yesterday, questioned why the murder-accused son of a Union Minister had not been arrested. "If you can arrest us, why not the murder-accused minister's son," the Congress leader told NDTV in an exclusive interview from a government guest house in Sitapur where she was detained. She called it a "complete collapse of the democratic, legal process" in Uttar Pradesh, where the Yogi Adityanath-led BJP government is in power.
