Ukrainian authorities have brought the hammer down on a group of Russian online casino sites operating without local permission.

On Tuesday, the Cyber Police of Ukraine announced that its officers, in conjunction with prosecutors in Kiev, had conducted searches of 15 locations connected to the operations of eight unauthorized online casino sites, including several domains that appear to be related to the Vulkan family of gambling sites.

The eight domains are: eldoradoclub.com, vulkanclub.com, 24vulkan.com, slotvulkanclub.com, estcasino.com, greencasino.com, anonymcasino.com and pharaonclub.com.

The report claimed that the police raids resulted in the seizure of over 100 computers, along with mobile phones, bank cards, an American bank checkbook, foreign currency, “Russian passports of members of a criminal group,” as well as unspecified weapons and drugs.
