Health condition of national award-winning singer Subir Nandi deteriorated once again yesterday as he had suffered from multiple organ failure at Singapore General Hospital. “Subir has suffered from multiple organ failure and is on life support. We should pray to the Almighty for him as his condition is not well,” said Dr Samanta Lal Sen, chief coordinator of National Institute of Burn and Plastic Surgery, who has been monitoring the singer’s treatment in coordination with the doctors in Singapore.
