Human traffickers are using "increasingly dangerous" tactics in a bid to dodge strict border controls, a Home Office spokeswoman has said.
It comes after 15 people were discovered in a lorry in Ilminster, Somerset, earlier today.
The spokeswoman said border and immigration officers were now assisting Avon and Somerset Police in their investigation.
We continue to work closely with law enforcement agencies both here and in Europe to target the organised crime gangs behind the majority of people-smuggling.
These criminals are constantly modifying their tactics in an attempt to evade strengthened border controls and we are seeing increasingly dangerous methods being used, including the use of sealed or refrigerated vehicles.
We would warn those who are tempted to put their lives in the hands of organised smugglers, that they are putting themselves and their families at risk.
