Around 500 protesters stayed put at the UP Gate with more pouring in from western Uttar Pradesh in the night on the call of the BKU, an influential farmers' union in north India.
The incident was reported in the morning when around 50 people, who came for the last rites of a fruit-seller, took shelter under the roof of a recently-built corridor to save themselves from getting drenched.
The mercury dipped to even lower levels in some parts of the city, recording 3.3 degrees Celsius and 3.4 degrees Celsius at Lodhi Road and Ayanagar, respectively.
An AQI between zero and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe".
