Firefighters in India's capital put out a smoldering fire Monday in the same building where a deadly blaze erupted the day before.
Forty-three people were killed Sunday when a fire ripped through the building that contained factory units. It was the worst fire in New Delhi in more than two decades.
Firemen fought the blaze Sunday, which broke out overnight with most inhabitants asleep, from 100 meters away as the alleys around the building were too narrow for trucks to enter.
Some companies provide sleeping quarters in their factories for workers who are generally poor migrants paid a meager salary.
The fire broke out in Sadar Bazaar - the city's largest wholesale market for household goods where electrical wires are strung all across narrow alleys of factories, shops, and apartments.
A preliminary probe into the fire suggested a short circuit triggered the tragedy, Indian news outlet PTI reported.
The building's owner, Rihan, who goes by one name, has been arrested as authorities probe possible failures to meet fire safety clearances.
