At least 19 people died and three others were injured Wednesday in a fire at a paper warehouse in Calcutta, an Indian police official told Efe.

The fire broke out about 3:50 a.m. in a central business area of the city, according to an official with the local police, who added that the blaze had been extinguished.

The four-story building where the fire started "has not been searched completely by the emergency teams, and so the number of dead or injured could rise," said the officer, who asked not to be identified.

The building had only one door and many of the people who were inside delayed in reacting to the emergency because they were sleeping, according to police sources cited by the media.

The chief minister of West Bengal state, Mamata Banerjee, announced a compensatory payment of 200,000 rupees ($3,735) for the families of each of the dead and said that in three days a complete report will be presented regarding the causes of the fire.

According to NDTV, West Bengal's top official for fire safety, Javed Khan, said that the building was an "illegal construction," just like hundreds of others in the city, given that monitoring the building of all such structures is very complicated.

The last big fire in Calcutta occurred in a hospital in December 2011 and killed 90 people. EFE
