The sudden death of renowned Bollywood singer Krishnakumar Kunnath, known by his stage name KK, after a concert in Kolkata has raised several questions about the arrangements at the venue. Kolkata Police has registered a case of unnatural death and is scrutinising CCTV footage to ascertain what happened before the singer was taken to the hospital. A video shows some people spraying a fire extinguisher outside the venue to try and disperse the large crowd. Many on social media claim that the AC was not functional at the venue and the heat became oppressive during the concert.
