ITV News Correspondent Emily Morgan reports
An international investigation is underway after a man was found dead inside a shipping container, along with 34 other people at the Essex port of Tilbury.
Superintendent Trevor Roe said it was too early to tell how the man had died and his death was the subject of a murder investigation.
Another 34, many suffering "severe dehydration and hypothermia" were discovered after port authorities heard banging and screaming from inside the container at around 6:30am.
Describing them as victims of "people trafficking", Supt Roe added that they had been in the container a "significant amount of time" and that now police were working with international agencies to establish their movements prior to arriving in the UK."
Police have established that the container arrived at the Essex dockyard on a P&O Ferries container ship from Zeebrugge in Belgium this morning.
However, they have yet to confirm where the container came from but Supt. Roe said the investigation will "span a number of countries."
Roe said: "We understand that the occupants of the container are from the Indian states. Exactly where they travelled from and their intended destination remains unclear."
He added that most were recovering fairly quickly, although "a handful" might be kept in for observation.
Roe said the group were being detained under immigration powers and will be taken to a reception centre.
