Fire breaks out at Mamata's hotel in Malda

Later, in a letter to Chief Election Commissioner V S Sampath and state CEO Sunil Kumar Gupta, TMC General Secretary Mukul Roy accused the EC of failure to ensure the safety and security of the chief minister who was a Z+ category protectee.

"Law and order in the state is now under the absolute superintendence, direction and control of the Election Commission, which has failed in its duty to ensure her safety and security," Roy said.

"I wish to bring to your notice that the safety norms and procedures were completely disregarded by the administrative machinery under your control," it said.

"This incident could have had fatal, disastrous consequences with repercussions in West Bengal and the entire nation," he said.

"One cannot rule out a deep, devious conspiracy behind this incident," he said.

Narrating the sequence of events, the letter said that the chief minister was staying at Golden Park Hotel in Malda when she heard a loud crackling sound when she was in the washroom.

"She called out for her aide who helped her to rush out of her room which was engulfed in thick smoke and the visibility was poor. On account of exposure to smoke and noxious fumes, she took ill," Roy said.
