Four Russians have been arrested during a police operation on the Costa del Sol Spain, after injecting their victim with what they maintained to be an experimental KGB virus, claiming he would die in 24 hours.The kidnappers seized a Russian businessman in a street last week in Estepona; a Spanish resort lying 20 kilometres (13 miles) to the west of Marbella. Marbella and it's glitzy neighbour, Puerto Banus plays host to the rich and famous and is the hedonistic playground for the rich and famous. The Russian crime gang threatened their hostage with the so called ‘deadly’ virus to scare him into paying a ransom amount of 12000 Euros ($16500) in return for the antidote, otherwise he would face death within 24hours according to a local report. The victim did endure some adverse symptoms including fainting, fever and vomiting. Their methods have been branded as bearing the typical hallmarks of a KGB style 'kidnap.' Armed Police officers from the organized crime squad in Málaga were on standby when the gang went to collect the ransom payment in San Pedro, just a few miles west of the notorious crime den of Marbella. The four Russians, three men and one woman, aged between 24 and 57, were arrested; three in San Pedro and one in Mijas. The gang now face charges of kidnap, torture and the illegal possession of firearms. This is the second kidnapping carried out by Russians in Estepona this year. A businessman’s wife and daughter were taken for a two million € ransom at the end of March. Police managed to release the captives in that case and made two arrests. The Russian mafia has been gaining pace in Spain, particularly in the Costa del Sol region due to the expanding property market, which has provided an opportunity for illicit gangs to launder money.
