The incident comes amid protests by farmers and the Opposition across the country over the three contentious farm legislations, which were passed by the Parliament last week and got presidential assent on Sunday.

Farmers have expressed apprehension that the laws would pave a way for the dismantling of the minimum support price system, leaving them at the "mercy" of big companies.

Delhi Congress chief detained

Kumar said a protest march from Rajghat to Raj Niwas was also scheduled but police detained party leaders and workers before it could begin.

"We wanted to submit a memorandum to the Lt governor against the farm bills passed by Parliament but we were detained by the police. The Congress will not rest till the Modi government withdraws its anti-farmer bills," he said.
