A high-stakes Danish poker pro was found guilty of cheating at online poker by a Copenhagen City Court last week.

Peter Jepsen, a well-known high-stakes online player with success pre-dating Black Friday, received more than two years behind bars and a €3.5 million fine for a six-year cheating spree that involved Jepsen installing malware on other players’ computers, according to local media.

From 2008 to 2014, Jepsen would run the scam against other high-stakes regulars, usually at high-profile European Poker Tour stops. He would gain access to their laptops and install the software. Once installed, he would have access to their hole cards.

After complaints from several players, the Danish authorities launched a five-year investigation and trial. During the trial, there were three witnesses that testified that they were involved in the scam. The two men and a woman that testified admitted that they were involved in installing the software that Jepsen used.

Along with the jail time and a seven-figure fine, the government confiscated $3.9 million from Jepsen, roughly the amount that he won from his opponents using an unfair advantage. Originally, the court felt that a three-year jail sentence was suitable, but six months was taken off the initial sentence because has been long overdue, according to the prosecutor in the case.

Jepsen was formerly sponsored by Betfair and played under the screen name “Zupp.” His live resume, on the other hand, is somewhat sparse. He has four career live tournament cashes for a total of $604,458. He won EPT Warsaw in 2007 for $415,679.

Jepsen has already filed for an appeal.
