Kolkata Police has registered a case of unnatural death over the demise of renowned Bollywood singer Krishnakumar Kunnath popularly known as KK, a senior officer said on Wednesday.
The case has been lodged with New Market Police Station under whose jurisdiction falls the five-star hotel where KK had put up and felt unwell before being taken to a hospital on Tuesday night, he said.
An initial probe has revealed that the 53-year-old singer, who was on a two-day tour to Kolkata to perform at two college programmes, was "almost mobbed" by fan followers at the hotel where he had returned after performing at Nazrul Mancha auditorium in the southern part of the city, he said.
"The singer had allowed a couple of fan followers to take snaps with him, but then he refused to carry on with the selfie session. He left the lobby and then went upstairs where he had reportedly stumbled and fallen on the floor. People who were with him informed the hotel authorities," the officer said.
KK was then rushed to a private hospital in the southern part of the city where he was declared "brought dead" by doctors, he said, adding that probably because of the fall, the singer had two injuries, one on the left side of his forehead and another on his lips.
"He was brought to the hospital around 10 pm. It's unfortunate that we could not treat him," a senior official of the hospital said.
Doctors at the hospital said they suspected "cardiac arrest" to be the cause of the death.
"The autopsy report will throw light on the exact cause of death. We are waiting for it," the police officer said.
Meanwhile, the singer's wife reached the city and went to the hospital where his body has been kept.
West Bengal Chief Minister Mamata Banerjee on Wednesday condoled KK's death.
"The sudden and untimely demise of the Bollywood playback singer KK shocks and saddens us. My colleagues have been working from last night to ensure that all requisite support is given for necessary formalities, his rites and to his family now. My deep condolences," she tweeted.
Banerjee, while speaking at a programme in Bankura, said she has cut short her tour and will try to reach Netaji Subhas Chandra Bose International Airport in Kolkata and pay her last respects to the mortal remains of KK.
She said the state police will give gun salute to the deceased singer.
"KK was a youth icon. We have lost a great singer. I have spoken to his wife who has arrived in Kolkata. Depending on the weather condition, I will try to reach NSCBI Airport to pay last respect to the singer. The state police will give gun salute to him," she said.
The singer had performed at Nazrul Mancha on Monday evening also in a concert organised by Vivekananda College. He was scheduled to return to New Delhi on Wednesday.
Initial hits such as 'Pyaar Ke Pal' and 'Yaaron' made KK popular among the youths of the country. As a playback singer, he has recorded Bollywood numbers such as 'Ankhon Mein Teri' (Om Shanti Om), 'Zara Sa' (Jannat), 'Khuda Jaane' (Bachna Ae Hasino) and 'Tadap Tadap' (Hum Dil De Chuke Sanam).
A versatile singer, KK has also recorded songs in Tamil, Telugu, Kannada, Malayalam, Marathi and Bengali, among other languages.
