Meanwhile, preliminary findings of the post-mortem conducted on renowned Bollywood singer Krishnakumar Kunnath have ruled out any foul play and indicated that he died due to a cardiac arrest, a senior police officer said on Wednesday.
Popularly known as KK, the singer passed away following a live concert in Kolkata. The report also said he had prolonged cardiac issues.
"The initial report suggested that the singer died because of myocardial infarction. There was no foul play behind his death. Clinical examination also found that the singer was having prolonged cardiac issues," the officer said, adding, the final report will be available after 72 hours.
KK was declared "brought dead" by doctors of CMRI hospital in Kolkata where he was rushed to after he "fell unconscious" upon his return to a hotel from a concert in Nazrul Mancha in south Kolkata on Tuesday night.
