While the news of Irrfan Khan's sickness was first revealed by director Vishal Bhardwaj when announcing the delay in his upcoming film on the female gangsters of Mumbai, the actor's tweet on 5 March came as a shock for many.
Writing a long post, the actor indicated that he has been suffering from a rare disease that has not yet been completely diagnosed.
While the nature of the disease is not known yet, the actor has assured followers on Twitter that he will reveal it after all the clinical tests have concluded.
