According to family sources, Puneeth suffered a heart attack while working out at a gym. Immediately he was shifted to Vikram Hospital. Dr Ranganath Nayak stated that his condition was critical when he was brought to the hospital. But the efforts of doctors to revive him went in vain.

Puneeth's health worsened on Thursday evening but he did not visit a doctor. He went to the gym in the morning and developed chest pain. He was taken to a private clinic where ECG was done. During check up, his condition worsened and he was rushed to Vikram Hospital, where he succumbed to cardiac arrest.
