The police have also registered 29 cases following the Supreme Court order on sale of old firecrackers, a senior police official said Monday.
Two days before Diwali, the national capital recorded its worst air quality of the season on Monday, with the pollution levels inching towards "severe plus emergency" category due to a change in wind direction and rampant stubble burning in neighbouring states.
Authorities predict the air quality to worsen during Diwali as they say burning firecrackers will spike air pollution to 'very severe' levels.
