A global positioning system (GPS) installed in a luxury car stolen in Milan on January 5 led to its recovery at the Athens airport car park on Saturday and the arrest of the man who went to collect it, it emerged yesterday. Italian police tipped off their Greek counterparts after the insurance company notified them of the whereabouts of the silver Mercedes CL 600. Greek police kept the vehicle under surveillance and on Saturday arrested Maxim Ditsman, a 32-year-old Russian, when he went to collect it. Ditsman told police he had taken possession of stolen vehicles at the airport from all over southern Europe, after their engine and chassis numbers were changed and number plates and registration plates replaced with forged Russian ones in their country of origin. Police suspect the Russian mafia has been using the car park at Eleftherios Venizelos international airport regularly as a transfer point for stolen cars destined for sale in Russia. Some 4,000 men of the Kosovo Police Service (KPS) serve alongside 4,000 international UN police force in the UN-administered Serbian province.
