Rio de Janeiro: With the World Cup football tickets it had originally bought being caught in the hands of alleged scalpers, Reliance Industries yesterday said it is investigating how the much-coveted and expensive tickets ended up in Brazil's black market.

Match Hospitality AG, a company appointed by World Cup organiser FIFA to sell hospitality packages that include private suites at stadiums and gourmet catering, said 59 tickets bearing RIL's name were found with the scalpers who resell tickets, usually for a hefty profit.
