Essex Police said Border Force staff were taking the lead on the incident as it "relates to immigration offences". Matthew Broad, from East of England Ambulance Service said "with the numbers being over 60, we launched our full major incident plan and sent resources including our hazardous areas response team so we could ensure that all those people were thoroughly medically checked." He added: "We do know from experience now that patients that have been in containers or lorries for some period of time can be dehydrated, and suffer other medical effects."
A Home Office spokesman said "four Polish nationals, who were driving the vehicles, have been arrested on suspicion of facilitating illegal immigration. They have been taken to separate police stations and will now be questioned by the Home Office's criminal investigations team while enquiries continue."
