When carefully inspecting a coach from Madrid and bound for Paris, the dogs of the Special Unit of Canine Guides, displaced from Bilbao to support the device, detected between the luggage of the trunk of the bus two suitcases that possibly contained drugs. It was then when they opened their guides that they saw that, in fact, there were 38 bags plasticized with what at first sight looked like marijuana.
After sounding the alarm and carrying out the necessary inquiries, they were able to find out that the owner of the suitcases was one of the passengers of the bus, so that, although he denied any connection with them, he was arrested and brought, together with the drug, to court.
