The charred body of a woman from Bangladesh was found inside a guesthouse in the Free School Street area in central Kolkata on Saturday after a fire broke out in the building, police said.
The blaze erupted around 4am due to a short circuit, following which three fire tenders were pressed into service, they said.
Fire brigade personnel recovered the body of a woman in a charred state from the building, a police officer said.
The woman was taken to SSKM hospital, where she was declared dead, he said.
Another man from the state's Murshidabad district, who received burn injuries in the incident, was discharged after treatment.
Eleven rooms of the guesthouse were damaged in the fire, the officer added.
