Spanish authorities have arrested 83 people - including 28 professional tennis players - following an investigation into match-fixing.
Among the 15 arrests were leaders of the criminal organisation, while a further 68 people have been investigated, the Spanish Civil Guard revealed in a statement.

Police said the organised group bribed the players to guarantee predetermined results and used the identities of thousands of citizens to place worldwide bets on the matches.
Gang members would attend the matches to ensure the player complied with the prearranged results.
Its officers searched 11 addresses in nine Spanish provinces, finding €167,000 (£151,000) in cash, as well as a handgun, stolen identity documents, jewellery, more than 50 electronic devices and five high-end vehicles.

The Guardia Civil said on Thursday that 83 people were implicated in the racket, among them 28 players in the ITF Futures and Challenger categories.
Professional tennis' anti-corruption body a year ago complained about irregular activities at games, including prearranged matches, at the lower-tier ITF Futures and Challenger tournaments. They also gave orders for "other members of the group" to place bets at the "national and global level".
"Those now under arrest ran the money through different accounts before finally transferring it to those under their control, always using false names", said police.More news: Semi-truck driver in deadly Humboldt Broncos crash pleads guilty
