Three men were arrested by Indian police in a suburb of Delhi on Tuesday after bets of 5.4m rupees (�77,000) wer placed on the outcome of the first Test in Bloemfontein.

Various items, including computers, mobile phones and a calculator were seized during the raid.

The Agence France Presse quoted a police spokesman as saying: "We are currently questioning these three suspects to ascertain if a bigger and larger network of bookies are involved, and if any of the betting activity has links with any player."

South Africa won the match by nine wickets after India collapsed in their second innings on the fourth day.

UCB president Percy Sonn said: "We have reminded our players and team management once again about the need for them to be vigilant regarding possible approaches from bookmakers or others involved in gambling on cricket.

"We have received no communication from the authorities in Delhi on the matter which is being reported in the media.

"However, we will assist with any possible investigations and will take our lead from the ICC."
