A 15-year-old Afghan immigrant was found dead in a truck carrying croissants at the port of Igoumenitsa on Thursday.
According to reports, the youngster had stowed away in the truck with several other irregular migrants.
However, after a while, the atmosphere in the vehicle became stifling and the stowaways abandoned the vehicle.
The 15-year-old, however, had already lost consciousness and was found dead later by port officials.
The Afghan teenager had registered a week earlier with a center for the protection of minors in nearby Konitsa.
A coroner was due to establish his exact cause of death.
