Even as authorities claimed that the blaze started in 1Above, where all the casualties were reported, the pub sought to push the blame on an unnamed adjoining premises and Mojo's Bistro, located a floor below, all of whose patrons escaped safely.
1Above blamed Mojo's Bistro for not having an emergency exit, leading to overcrowding of 1Above's escape avenues.
"We believe that all their guests were told to go through our premises as we have an emergency exit," according to a statement from 1Above.
The pub claimed that that it conducts quarterly fire safety and crisis management training and it has over 10 fire extinguishers and adequate fire safety signatures at its premises as is required under rules.

The 1Above management also said their property did not keep any gas cylinders near their rooftop premises and that the gas bank was maintained on the ground floor.
But eyewitnesses also said the cylinders were kept on the ground floor and were connected to the 1-Above kitchen on the rooftop.
"Our staff were able to evacuate all our guests and themselves out to safety with zero injury. There were no cylinders on our premises," Mojo's said in a statement, which also claimed the facility complied with requisite fire safety norms, certificates and procedures.
The staff, it said, was "thoroughly trained" in fire drills due to which all the guests could be evacuated.
