Three vehicles were intercepted at the customs of Beni-Enzar in the space of three hours, between 9 am and noon.
Inside the cars, officials found a teenager and two other men, who are between 20 and 21 years old.
One of them was hidden behind the rear seats and the other two were in the dashboard.
Two of the three had to be stabilized by doctors after suffering symptoms of asphyxiation, disorientation and generalized joint pain due to the way they had traveled.
A fourth truck was then searched in the Spanish port of Melilla and the authorities found a 20-year-old man at the base of the vehicle. He had to be helped out of the truck because of the dangerous nature of his hiding place.
It is believed that the man had “benefited” from the carelessness of the driver to get to the scene.
The Civil Guard said the drivers of the intercepted cars, all registered in Morocco, were arrested and go to court. They are described as being all men, of Moroccan nationality, aged 19, 30 and 31 years.
None of them has any connection with the city of Melilla.
