On 3 February 2010, the Spanish national police arrested Florencio Carro Ruiz (alias: Netkairo) as the suspected leader of the DDP Team. Two additional arrests were made on 24 February 2010. Jonathan Pazos Rivera (alias: Jonyloleante) and Juan José Ríos Bellido (alias: Ostiator) were arrested on the suspicion of being members of DDP. On 18 July 2010, Matjaž Škorjanc (alias: Iserdo), the creator of the "Butterfly bot" malware, was arrested in Maribor by Slovenian police for the first time, but released due to lack of evidence. He was arrested again in October 2011. In December 2013 Škorjanc was convicted in Slovenia of "creating a malicious computer program for hacking information systems, assisting in wrongdoings and money laundering." He was sentenced to 4 years and 10 months imprisonment and fined €3,000 ($3,000). The court also ordered the seizure of Škorjanc's property acquired with the proceeds of crime. After he appealed the verdict his fine was in February 2015 raised for additional 25,000 EUR.
