Senior Congress leader Sachin Pilot, who was on his way to meet the families of farmers killed in the violence that broke out in Uttar Pradesh's Lakhimpur, was detained this evening. "The Uttar Pradesh government is certainly trying to hide something," he said on several political leaders being stopped from going to Lakhimpur Kheri. The Congress leader said he hasn't been informed by when he will be released. "I have just been put here in the guest house. I have been told I can't go," he said.
