Police forensics officers investigate a truck and its container where 39 dead bodies were discovered in Grays, Essex, southeast England.
Video shows the red Scania tractor unit (the front part of the truck) and white trailer at Waterglade Industrial Park cordoned off by police.
Forensics are seen examining the tractor unit.
Police said the truck is from Bulgaria and that the 25-year-old driver has been arrested.
Local Member of Parliament Jackie Doyle-Price tweeted that “people trafficking is a vile and dangerous business.”
It has since been reported by ITV News that the victims were all Chinese nationals.
ITV stated: "The 39 people found dead in the back of a refrigerated lorry trailer were all Chinese nationals, ITV News has learned."
