Marbella FC owner Alexander Grinberg was arrested at a dawn raid at a luxury Marbella villa this morning.
Grinberg, pictured earlier this year with ex-mayor Jose Bernal and who brought the club in 2012, was detained by Guardia Civil officers as part of a co-ordinated operation against the Russain mafia, known as Solntsevo, in both Marbella and Mijas.
Six other Russians have been arrested and Marbella FC offices at the Municipal Studium were also searched as officers removed files.
The operation, described as the biggest against the Russian mafia on the Costa del Sol, was co-ordinated by Guardia Civil officers in a helicopter.
The police operation is also investigating Aguas Sierra de Mijas S.A., whose board of directors is composed of Russians.
The accused are charged with money laundering and belonging to a criminal organisation.
