Swedish state sponsored betting operator Svenska Spel has blocked 14 punters in what is being described as serious fraud occurring in the firm's internet poker operation.
The 14 users are accused of using a form of software that gave them an advantage. The operator began noticing the discrepancies in October 2012 after players monitoring the games submitted their concerns.
The frozen accounts currently hold a balance of $108,000, but it is estimated that they have taken in $1.8 million since the scam began.
Svenska Spel acted quickly on the issue, notifying Swedish police of the incidents and working hard to notify customers that they are in control of the situation.
Commenting on the matter Svenska Spel CEO Lennart Kall said: “Svenska Spel's business is based on great responsibility for our customers' gaming habits and game security. I welcome the fact that the police have taken on the matter".
The firm's Press Officer Johan Söderkvist added: "We suspect that some kind of gambling analysis software was used to gain advantage. Overall, there is $1.8 million that was recorded during this time, but we can not establish with certainty that the players used these illicit funds at all times while playing."
