There is an increased police presence in the French port of Calais after dozens of migrants attempted to storm a ferry bound for Dover.
Some migrants, seeking to enter the UK, have tried to jump into cars as well as lorries.
Police are now giving guidance to drivers to help them avoid unwittingly taking on migrants, as Ben Ando reports.
