LJUBLJANA, Slovenia (AP) — European police say Slovenian and Croatian security have busted an international crime syndicate involved in sports corruption, illegal betting and trying to fix soccer matches in several countries including Serbia, Macedonia and the Czech Republic.

Europol said Tuesday that 13 house searches and 15 vehicles searches in different locations in Slovenia and Croatia have been carried out and 11 people have been arrested.

They say that the "network had created an illegal web platform in order to convey large bets on major Asian bookmakers."

Europol say the investigation began in March 2017, when Slovenian police "realized that an organized crime group had created different websites as part of an online illegal betting platform used to place bets on manipulated sport events that took place in multiple European countries."
