BBC News reports "A German national has been arrested on suspicion of facilitating the unlawful entry of people into the UK". The group included a boy aged 15. Medical teams responded to the incident and most of those found were suffering from dehydration.
The vehicle had travelled over into the UK from Calais, France, but how the migrants had arrived in France is not known.
Police investigations continue.
While there are obvious concerns for the people involved in both incidents it highlights just how easy it could be for disease or would-be terrorists to enter the UK.
