Four people have been arrested this week in connection with the deaths of 39 people found in a container at the back of the truck, at an industrial park in Grays, Essex.
Here's what we know about the investigation:
- The suspects: Mo Robinson, a 25-year-old Northern Irish truck driver, was arrested Wednesday on suspicion of murder. On Friday, police arrested three more suspects — a 48-year-old man from Northern Ireland, and a man and a woman, both 38. They were arrested on suspicion of manslaughter and trafficking-related offenses.
- Identification process starts: Autopsies have started on some of the victims as police work to identify them. Police have said the eight women and 31 men inside the truck were Chinese. However, China contests the claims, saying it is "not yet possible" to confirm the victims' nationalities.
- The container's origins: The truck container was transported from Belgium to the UK on a ferry called the Clementine, CNN has ascertained. The owner of the trailer also shared GPS tracking information with British Police. A lawyer representing GTR, the company that owns the trailer, said the trailer allowed for real-time monitoring of the temperature, information that is shared with the truck tractor and the driver.
