A major fire broke out in the VICCO Laboratories unit in Nagpur, leading to the collapse of its ground and two upper floors, an official said on Monday.
The blaze erupted around 10.40 pm on Sunday in the unit located on plot no. S-89 in Hingna industrial area here in Maharashtra, Nagpur Municipal Corporation's chief fire officer Rajendra Uchke said in a release.
There was no report of any casualty so far, he said.
