Northern Ireland police say they have arrested a man on suspicion of smuggling 35 Afghan immigrants into England in a shipping container, during which one man died.

The 34-year-old man was arrested Tuesday in the Northern Ireland town of Limavady. Police say he is being interrogated on suspicion of manslaughter and aiding the illegal entry of the Afghans into the United Kingdom.

Dock workers in the port of Tilbury, east of London, heard the Afghans screaming and pounding the walls of the container as it was unloaded from a cargo ferry Saturday.

One man, 40-year-old Meet Singh Kapoor, was pronounced dead at the scene. The others — identified as three Kabul families including 13 children — were treated for dehydration and hypothermia.
