A man has been arrested over the death of an Afghan man found in a shipping container at the Tilbury Docks on Saturday.
The 34-year-old from Limavady was detained by police in Northern Ireland at Banbridge on the A1 on suspicion of manslaughter and facilitating illegal entry into the United Kingdom.
He is currently in the custody of the Police Service of Northern Ireland (PSNI) pending his transportation to the mainland for questioning by Essex Police.
PSNI officers are also carrying out a search of his home address to assist the Essex Police investigation.
The dead man, named as Meet Singh Kapoor, was one of 35 Afghan stowaways found shut inside the container.
Acting Detective Chief Inspector Martin Pasmore, of Essex Police, said: "This is a fast-moving investigation which has already involved a number of police forces and law enforcement agencies from across the United Kingdom and Europe.
I am very grateful to officers from the PSNI for their assistance this morning. We will continue to work closely with all of our policing colleagues as we pursue our investigation to bring those responsible for this crime to justice."
