Priyanka Gandhi Vadra said today that she had been "illegally held" indefinitely by the Uttar Pradesh government for over 24 hours and targeted Prime Minister Narendra Modi over a Union Minister' son accused of running over farmers at a protest in Lakhimpur Kheri on Sunday. "Why is the opposition arrested without any order and a man who has committed such a horrendous crime, he is not arrested. PM Modi, arrest him, not people like us," Priyanka Gandhi told NDTV in an interview from a government guest house in Sitapur, where she has been detained since early Monday morning.
