A lorry driver is due to appear in court charged over the deaths of 39 people found in a refrigerated trailer in Essex.
Maurice Robinson, 25, of Craigavon in Northern Ireland, is due to appear via video link at Chelmsford Magistrates’ Court on Monday.
The bodies were found in a trailer in the early hours of Wednesday on an industrial estate in Grays.
DNA tests are being carried out in Vietnam to help to identify the dead.
Mr Robinson is charged with 39 counts of manslaughter, conspiracy to traffic people, conspiracy to assist unlawful immigration and money laundering.
Another driver who brought the container to Zeebrugge before it crossed the Channel was arrested at the port of Dublin on Saturday, according to the Belgian prosecutor’s office.
Essex Police said the man was “a person of interest” in their investigation.
“We are liaising with the Garda via telephone as this man is currently held outside the jurisdiction of the law of England and Wales,” a spokesman said.
Three other people arrested in connection with the deaths were released on bail on Sunday.
