Multiple call centers across Europe controlled by a criminal organization involved in online investment fraud were taken down this week following a cross-border investigation started in June 2022.

Law enforcement from Bulgaria, Cyprus, Germany, and Serbia found that suspects operating out of these call centers tricked victims into investing large amounts of money in fake cryptocurrency schemes, also known as 'Pig Butchering' cryptocurrency scams.
