TNP obtains Italian court paper that indicates Tan is the leader and organiser of a global match-fixing syndicate.
The Cremona investigation papers chronicle Tan's alleged involvement in the rigging of 33 matches in Italy's top two leagues, Serie A and Serie B, over the last two years.
Europol reveals more than 680 suspicious matches worldwide, including World Cup and European Championship qualifiers and a Champions League game played in England.
It says operations are run out of Singapore, with bribes of up to 100,000 euros (S$170,000) paid per match.
Tan's second wife, who wants to be known only as Madam Lim, tells TNP that he walked out on her and their two sons 10 years ago, when they needed him the most.
She says he was jailed for less than a year after being convicted of being an illegal horse-racing bookie in the 1990s, and that he loves betting big on horse racing and football matches.
Tan is arrested by the Corrupt Practices Investigation Bureau (CPIB).
The 12-hour joint operation early Tuesday morning involving the Criminal Investigation Department, CPIB and Police Intelligence Department also led to 13 other arrests, which include two women.
Five are being further detained under the Criminal Law act and nine are out on bail.
