Ten labourers, who were trapped in the under-construction building, were rescued and the fire was brought under control after two hours.
"10-12 labourers were working on the interior decoration of the building, which is not operational," senior police inspector Chandrakant Bhosle told reporters.
As many as 16 aerial ladder platforms (ALP) were pressed into service which managed to douse the flames with the help of six fire tenders and as many water tankers, fire officials said.
The fire broke out at around 10.45 AM on the 12th floor of the First International Financial Centre (FIFC) high rise building and spread to the 13th floor, they said.
