Police on Friday sealed Delhi’s borders to stop the entry of the farmers during a protest march organised by the Shiromani Akali Dal to mark a year of the enactment of the contentious farm laws.

A video being shared on social media showed several Sikhs protesting vociferously against being singled out and stopped.

They are seen demanding to know from a purported policeman at the spot why others are being allowed to pass and only Sikhs were being stopped. To this, the purported policeman says: “Bhaisaheb, I am doing what I have been ordered. What the senior officers have ordered, that is what I am doing.”

Delhi police made no comments about the video till late on Friday.

Sources said the police were under instructions not to allow Punjab-registered vehicles inside the capital.

Akali Dal leader Harsimrat Kaur Badal said it was an undeclared emergency and condemned Delhi police for allegedly detaining party workers who arrived in groups to take part in the “Black Friday” protest march. The protest march was organised from Gurdwara Rakab Ganj Sahib to the Parliament building.

The Akali Dal had left the BJP-led NDA over the farm bills.
