According to some Spanish newspapers, 44-year-old Tjalling van K.V. was "one of the largest drug barons in Europe" and "Ibiza's biggest ecstasy dealer".

Van K.V. has lived on the Spanish island, famous for its party scene, for the past eight years. He was known to the locals as "Carlos".

Police got suspicious when a truckload of 138 kilogrammes of chocolate arrived at the Ibiza port last week from the Spanish mainland. The chocolate was unbranded and marked only as "pure chocolate". The two truck drivers said they had hallucinations after they tasted the chocolate. Each of the 5,000 bars of chocolate was found to contain LSD.

A police officer disguised as a truck driver took the shipment to Van K.V.'s house in Platja d'en Bossa. When the Dutchman took possession of the shipment he was immediately arrested. At his house, police found 32,000 ecstasy pills, 12 kilogrammes of methamphetamine and 12,000 euro in cash.

Van K.V. claimed he was holding the shipment for a friend.
