The covert operation started about seven months ago.
The target was to crush an alleged international football match-fixing syndicate with suspected Singapore links.
On Thursday, The Telegraph reported the success of the sting, which resulted in the arrests of six men in Britain, including a Singaporean, who is said to have played a vital part in the syndicate.
They were arrested on suspicion of fixing English football matches.
The New Paper can now disclose that anti-fraud agency SI Sports Intelligence was the one who started the ball rolling in May this year.
Said Mr Michael Pride, director of operations at SI Sports Intelligence: "I can't stress enough that these arrests are significant because the people involved aren't known for 'one-offs'.
Their syndicate has been around for many years and has been set up for that very purpose."
The agency had infiltrated the "kelong" outfit when its runners had tried to source for funds.
Slowly, the Singaporean man, 33, began to confide in the SI Sports Intelligence undercover operators.
The suspect, allegedly an associate of convicted Singaporean match-fixer Wilson Raj Perumal, claimed in numerous correspondences that football matches in Britain, other parts of Europe, Australia and South-east Asia could easily be fixed for a fee.
He had even boasted that Wilson Raj was his boss.
