Bollywood megastar Amitabh Bachchan has refuted the reports, claiming his miraculous escape from a car accident last week in Kolkata, when one of the rear wheels of his Mercedes got detached. Big B took to his Twitter handle to clarify that he didn't meet any accident and is very much fine. He tweeted, "I am informed by concerned well wishers and media, that I had a close escape from a car accident in Kolkata .. that is incorrect .. there has been no accident .. I am well." The 'Piku' actor was in the West Bengal capital for the inaugural programme of the 23rd Kolkata International Film Festival.
