Congress leader Priyanka Gandhi Vadra, who was detained on her way to violence-hit Lakhimpur Kheri post-conflict during a farmers’ protest, asked Prime Minister Narendra Modi the basis of her detention via a tweet on Monday. The politician complained that she had been in detention for almost 24 hours without any legal proceeding or first information report (FIR) and asked the government why the person responsible for the killings of the farmers was still free.

“@narendramodi, your government has kept me in detention for 28 hours now without any order or an FIR. The person who crushed the farmers has not been arrested yet. Why?” asked Gandhi in a tweet written in Hindi.

The Congress leader also attached a video alongside her post that shows an unidentified vehicle running over the protesting farmers.

At least eight people, four of them reportedly farmers and a local journalist were killed on Sunday during clashes following a protest against the farm laws.

The farmers’ protest, which was being held against the visit of UP Deputy CM Keshav Prasad Maurya’s visit took a violent turn after at least one car, allegedly driven by Union minister of state Ajay Kumar Mishra Teni’s son Ashish Mishra, hit the protesting farmers at Tikunia village in the district, prompting an angry crowd to burn two vehicles and widen their agitation.

Earlier, Chhattisgarh Chief Minister Bhupesh Baghel on Monday slammed the BJP-led Uttar Pradesh government after he was stopped to land at the Lucknow airport, and asked whether civil rights have been abolished in the northern state.

Baghel was scheduled to visit Lakhimpur Kheri in UP where at least nine people were killed in the violence since Sunday.

The Uttar Pradesh government has requested the Lucknow airport authority not to allow the arrival of Chhattisgarh Chief Minister Baghel and Punjab’s Deputy CM Sukhjinder S Randhawa, who had announced plans to visit Lakhimpur Kheri in view of the violence there.
