The Equity Poker Network discovered a collusion ring operating on its network, according to a press release issued Friday.

According to the announcement, EPN’s internal fraud team discovered some irregularities that sparked an investigation. As a result of the investigation it was determined that a group of players were involved in fraudulent activities on the network.

Subsequently the perpetrators’ funds were confiscated and the offending accounts permanently banned. No other information was disclosed regarding the “illegal player conduct.”

Players negatively impacted by the cheating can expect to be reimbursed for their losses.

“EPN will ensure that all players affected by this fraudulent activity are refunded, and the distribution of funds to these affected account holders will be facilitated shortly,” the press release states.

There have been recent reports on the poker forums of at least one player having funds confiscated for violating the site’s terms and conditions. It is unclear if the account is related to the fraudulent activity.

The Equity Poker Network launched in November 2013 with flagship skins Full Flush Poker and IntegerPoker. The network has enjoyed steady growth since launch and now appears in the top 50 online poker networks, according to traffic data provided by PokerScout.
