Heavy traffic snarls were witnessed on Sunday in several parts of Delhi following protests by AAP workers against the summoning of Chief Minister Arvind Kejriwal by the CBI in the excise policy case.

Vehicular movement was choked at the protest sites of Anand Vihar Terminal, ITO Chowk, Mukarba Chowk Peera Garhi Chowk, Lado Sarai Chowk, Crown Plaza Chowk, Dwarka More Sec 6 and Sec 2 Chauraha, Pecific Wala Chowk Subhash Nagar More, Prem Wari Chauraha Ring Road, New Delhi Railway Station Ajmeri Gate Side, Bara Hanuman Mandir, Karol Bagh Chowk, IIT Crossing, ISBT Kashmiri Gate, Raj Ghat and NH 24 near Murga Mandi Gazipur. Serpentine queues of vehicles clogged the roads owing to the protest.

Commuters stuck because of the protests at NH-44 and GT-Karnal Road tweeted pictures that showed long queues of vehicles. Moving at a snail’s pace in bumper-to-bumper traffic, many commuters tagged the police in their social media posts and requested them to manage the situation.

Police officials, along with the traffic unit deployed at multiple locations, persuaded the protesters to move from the roads and allow vehiclular movement to flow.

“We have deployed sufficient force at these locations. But the protesters are on a sit-in, so we are persuading them to move because they are causing heavy traffic jams. If they are refusing to cooperate, we are removing them from the spot,” a senior police official said.

The Delhi Police stepped up security outside the CBI headquarters as Kejriwal appeared before the agency for questioning in connection with alleged irregularities in the now-scrapped excise policy, officials said.
