Guardia Civil officers seized 3.4 tonnes of cannabis resin in Guadarranque after Spain’s SIVE coastal surveillance network detected a fast launch entering the Arroyo Cachón near Puente Mayorga.
Land units despatched to the area found a rigid hull inflatable boat abandoned in the estuary and received information that two four-wheel drive vehicles had been used to unload drugs.
One of the vehicles was later spotted entering a garage in Guadarranque.
As the officers entered the building, two smugglers fled the scene while a third was arrested, according to the Guardia Civil.
Inside the garage the officers found a vehicle with fake licence plates, a tractor and a vessel. A 9mm pistol was also found inside one of the vehicles.
Officers also seized 109 bales of cannabis resin weighing 3,380 kilograms.
