I read in a news article that Vijay Mallaya's passport was cancelled. When that happens to common man, it means that the only travel document available has been cancelled, so the person is unable to travel anywhere. The government might've cancelled the passport due to the reason that Mr. Vijay might've had another country's passport. India does not allow dual citizenship, hence India's passport was cancelled. This is just a technicality and does not hinder his travel anywhere on his potential second country's passport. If the government really wanted to nab him, there would've been a red corner notice through Interpol for him to be arrested by any other country's police. Kindly note that this did not happen.
