Mamata Banerjee was seen consoling KK's wife and children, who flew to Kolkata on Wednesday to take him home to Mumbai.
The singer's body was brought to the Rabindra Sadan after the post-mortem was conducted at the state government-run SSKM Hospital earlier in the day.
His mortal remains will be taken to the Netaji Subhas Chandra Bose international airport and handed over to his family, who will fly to Mumbai with the body.
KK was declared 'brought dead' by doctors of a hospital where he was taken after he 'fell unconscious' upon his return to the Oberoi Grand Hotel from a concert on Tuesday night, the police said.
The Kolkata police registered a case of unnatural death and have started an investigation.
The vocalist, who was known for his versatility, sang in different languages including Tamil, Telugu, Kannada, Malayalam, Marathi and Bengali.
