GUARDIA CIVIL officers in Spain have arrested two Brits after they intercepted drugs hidden in packets of coffee at Alicante-Elche airport.
The parcels had been flown in from Hong Kong and two English residents of El Campello, 36 and 37-years-old, have been arrested.
The Guardia Civil has described the synthetic drug as 80 times more powerful than cannabis.
A total of 12,200 grams of the substance has been discovered with an estimated street value of €3.5 million.
The operation began in mid-March, when Guardia Civil officers intercepted packages bound for a bar frequented by the English community of El Campello.
Spanish authorities put the pub under surveillance which resulted in the arrest of a 36-year-old suspect, who was collecting mail for the group that imported the drug, according to sources. The second suspect was arrested two days later at the Alicante-Elche Airport when he was trying to leave Spain.
