Bollywood singer Krishnakumar Kunnath aka KK died due a cardiac arrest, reports PTI referring to the preliminary findings of his post-mortem report.
Meanwhile, police also ruled out any chances of a "foul play" behind the popular singer's death.
"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," an officer told the news agency.
The final autopsy report will be available after 72 hours.
KK was known for songs like 'Pal' and 'Yaaron', which went on to become big hits among teens in the late 1990s, often heard during school and college farewells and teen cultural events.
Staff members of Nazrul Manch auditorium in South Kolkata said that the venue was overcrowded during the KK concert.
Many on social media claim that the AC was not functional at the venue and the heat became oppressive during the concert.
The singer's sudden death after a concert in Kolkata had raised several questions about the arrangements at the venue.
