The Home Office said tonight that 13 people found in a lorry in Kent, whose nationalities have yet to be confirmed, will be questioned later.
Officials had this warning for lorry drivers entering the UK:
Drivers and hauliers must take adequate steps to secure their vehicles from illegal immigrants trying to smuggle themselves across the border.
If a driver does not take these steps - and is found with people hiding in their vehicle - they will be issued with a civil penalty.
