With the recovery of one more body from fire ravaged Stephen Court, toll mounted to 25 today.
The body was found from the fifth floor of the building and its gender was yet to be ascertained, the police said.
The body, charred beyond recognition, was taken to SSKM Hospital for postmortem.
Several persons are still missing after a massive fire swept through the 150-year-old multi-storeyed heritage building housing offices and residences in Kolkata's busy Park Street on Tuesday.
A stench from one corner of the fifth floor had prompted the firemen to look for possible bodies hidden underneath the rubble that was being cleared by the Kolkata Municipal Workers employees.
Several persons had jumped from the burning floors to death.
