According to Relief and Rehabilitation Secretary Pravin Pardeshi, 65 people trapped on the fifth and sixth floor have been evacuated by the firefighters. Two helicopters of the Indian Navy were pressed into service to evacuate those trapped inside the building but returned without any success as nobody could be found on the terrace of the building in south Mumbai.
Contingents of the anti-terror force -- Force One and Quick Response Teams of Mumbai police assisted the fire brigade in trying to bring the blaze under control.
According to fire brigade sources, while the flames in the front part of the Secretariat have been weakened, fire was still raging on the rear side of the building.
Pardeshi said nearly 3,000 government employees and as many visitors were removed safely after the blaze started.
Relief and rehabilitation Minister Patangrao Kadam admitted that the government had never anticipated such a major fire at the seat of Maharashtra administration and added that the damage caused to the building would be assessed soon.
Chavan, Pawar and Home Minister R R Patil supervised the rescue efforts. Pardeshi said the fire was first noticed in an electrical fuse and soon a general alarm was sounded across Mantralaya asking people to rush out.
By 3 pm everybody, barring the 65 trapped due to "ballooning" of the smoke, had evacuated, he said. Those hospitalised included Chief Minister's Public Relations Officer Satish Lalit, PROs in Deputy CM's office Vishal Dhage and Sanjay Deshmukh and state Home Minister's PRO Kishore Gangurde. All of them had inhaled the smoke, he said.
Electric supply to the building was stopped. Asked if the Secretariat would remain closed on Friday, he replied in the negative.
Meanwhile, a Brihanmumbai Municipal Corporation official said that the fire brigade received the first call informing about the blaze at 2:46 pm, following which three fire engines, two water tankers, and an ambulance were rushed to the spot.
The injured persons have been admitted to various hospitals, including 11 at JJ and St George, three at GT Hospital and two at Nair Hospital.
Some of them have suffered suffocation, while others have sustained minor injuries to hands and legs, J J Hospital dean Dr T P Lahane said.
There were around 2,500 Mantralaya staffers in the building, apart from around 2,000 visitors when the fire broke out, a Mantralaya official said. The Mantralaya building typically houses around 8,000 employees on a normal working day.
