From modest roots, Sahara has pursued splashy deals.
In late 2010, it bought the Grosvenor House hotel in London and a year later acquired New York's Plaza Hotel, its two biggest overseas deals. In 2010 it looked into buying English Premier League soccer club Liverpool and the debt of film studio Metro-Goldwyn-Mayer, although neither deal materialised.
Roy's public profile is mostly linked to sport.
In 2011, Sahara paid $100 million for 42.5 percent of the Formula One racing team of liquor tycoon Vijay Mallya.
A year earlier, it paid $370 million for the Pune Indian Premier League cricket franchise.
Roy gives infrequent interviews but is not publicity-shy. His website features photos of himself with Bill Clinton and Mother Teresa and the caption: "The world steps aside for the man who never stops."
During British Prime Minister David Cameron's recent visit to Mumbai, Roy was among local business leaders to meet him. Sahara sent a photo of the two of them to reporters.
Roy portrays himself as fiercely patriotic. Sahara's logo features the Indian tri-colour and the company frequently uses an image of Bharat Maa (Mother India) driving a chariot pulled by four snarling lions.
