Grays, England (CNN)British police have launched a murder investigation after 39 people, including a teenager, were found dead in a truck at an industrial park 30 kilometers east of London on Wednesday.
Police said the container arrived by sea in Purfleet, Essex, early Wednesday morning from the Belgian port city of Zeebrugge. Just over an hour later, at around 1.40 a.m., ambulance workers called police to the truck, which was by then parked in an industrial estate in the nearby town of Grays.
A 25-year-old truck driver from Northern Ireland was arrested on suspicion of murder, police said.
