MUMBAI: A minor fire erupted on the fourth floor of Mantralaya, the Maharashtra government secretariat in South Mumbai, on Monday night, but no casualty was reported, Fire Brigade officials said. 

According to the officials, the fire erupted around 8. 30 pm and it was doused around 9.30 pm. 

"No one suffered any injuries in the fire that could have started due to a short-circuit," said a Fire Brigade officer. 

"The fire was confined to a computer and printer in one of the closed cabins of the urban development department on the fourth floor near the chamber of the urban development minister," he said. 

Due to the blaze, dense smoke engulfed the entire floor, the officer said. 

Four fire engines and three tankers rushed to the spot to douse the flames, said the officer, adding it was a minor fire. 

"False ceilings were removed at some places and operation of AC plant room was stopped for the time being," said the senior fire officer.
