Shiromani Akali Dal chief Sukhbir Singh Badal, senior party leader and Lok Sabha MP Harsimrat Kaur Badal, and several other members were on Friday detained by the Delhi Police even as allegations regarding the use of force to stop the party's "Black Friday march" by the authorities surfaced.

The SAD chief and others were booked for violating section 144 of CrPc, which prohibits large gatherings, and taken to the Parliament Street Police Station.

"We were here to protest... Delhi Police used force to stop us. Police sealed the borders... our workers were lathi-charged. (Arvind) Kejriwal government gave orders that we cannot gather at a gurudwara... central government also stopped us. This is undemocratic," Harsimrat told NDTV.

"We had clearly said this will be a peaceful protest," she was quoted as saying.

Earlier, massive traffic jams hit parts of the national capital, including Lutyens' Delhi and ITO as SAD members gathered at Delhi borders to mark one year of farmers' protest. Taking to Twitter, the Delhi Traffic Police informed about closure of roads at Jharoda Kalan border and suggested commuters to refrain from using these routes in view of the farmers' movement.

Two Delhi Metro stations near Tikri border with Haryana, one of the sites of the ongoing farmers' protests, were on Friday closed owing to security reasons, the Delhi Metro Rail Corporation said.

The three agriculture laws, which the farmers have been protesting against for several months now, were passed in Parliament on September 17, 2020, and SAD minister Harsimrat Kaur Badal had resigned from the Union Cabinet in protest.
