Police in the United Kingdom on Wednesday arrested a 25-year-old Northern Ireland man on suspicion of murder after 39 bodies were found in the back of a semi-truck in Essex, which is east of London.
Essex police said that 38 of the bodies were adults and one was a teenager.
Chief Superintendent Andrew Mariner said investigators are working to identify the bodies, which is expected to be a “lengthy” process.
The truck traveled from Bulgaria through the Welsh town of Holyhead, police said according to the BBC.
Police have cordoned off the Waterglade Industrial Park where the bodies were found.
