GUARDIA Civil officers have arrested a lorry driver on the A-31 in Villena (Alicante) after he was found to have nearly a tonne of hash in the back.
Police say they were carrying out a routine check on random vehicles heading in the direction of Madrid on Thursday when they discovered the illicit haul.
They said they had been about to let the lorry driver go, but his apparent nervousness aroused their suspicions.
A total of 14 parcels of ready-to-use marihuana, weighing 770 kilos (around 1,700lbs) was confiscated.
The driver, a 25-year-old man, has been arrested.
