Union minister's son Ashish Mishra - accused of murder in the farmer deaths at Lakhimpur Kheri - has been summoned for questioning, the UP police said. Two people who were at the location of the incident have been arrested, the police said. This is the first time the police has asked to question Ashish Mishra -- the son of junior home minister Ajay Mishra. An FIR against him was filed on Monday. The police pasted a notice outside the Union Minister's home, summoning his son for questioning at 10 am on Friday. The inaction so far had set off opposition allegations that the police are shielding the high-profile accused.
