Two new arrests have been made, but many doubts still hang over the identity of the victims.

The investigators are progressing. British police said Friday they made two more arrests in the case of 39 migrants found dead in a refrigerated truck in Essex, east of London. The two people in police custody are a 38-year-old man and woman from Warrington, in the north of England.

Their arrest is added to that of the driver of the truck, placed in custody as soon as the bodies are discovered and for whom the investigators obtained an additional period of detention. His home in Northern Ireland was raided, as were two other houses in the same area. The results have not been made public.

Doubts about the identity of the victims

The course of the container also seems to be better known thanks to its GPS plotter. The days before his macabre crossing, he crossed the Channel several times and traveled the north of France and Belgium, including Dunkirk, Lille and Bruges.

But since Thursday also appear many doubts about the origin of the 39 victims. After introducing them as Chinese nationals, the Essex police are now more cautious. Certain elements of identification could indeed change the situation. Several Vietnamese families in distress have made themselves known, almost certain that their relatives were inside the truck.
