Second arrest over Tilbury Docks container death
A second person has been arrested on suspicion of manslaughter over the death of man in a shipping container in Essex.
The dead man was one of 35 people from Afghanistan, including 15 children, found at Tilbury Docks on Saturday.
Police said a 33-year-old man from Londonderry had been arrested after voluntarily attending a police station in Essex.
He is due to be questioned by detectives later.
The suspect has also been arrested on suspicion of facilitating illegal entry into the UK.
A 34-year-old man from Limavady, who was arrested by the Police Service of Northern Ireland (PSNI) on Tuesday at Banbridge, County Down, is due to arrive in England later for questioning.
The migrants arrived in the UK on Saturday on a ship from Belgium and were said by police to be victims of people trafficking.
They were discovered after dock workers heard banging and screaming coming from one of the containers.
Those found inside were taken to hospital, with many suffering from the effects of severe dehydration and hypothermia.
The dead man has been named as Meet Singh Kapoor. He was 40 years old.
Initial post-mortem tests have proved inconclusive.
The 34 survivors include 10 men, nine women and 15 children, with their ages ranging from one to 72.
They are all in the care of the Home Office after being discharged from hospital and questioned by police. They are seeking asylum in the UK.
It is believed the group was in the container for about 18 hours.
