A major people smuggling network accused of transporting around 1,000 migrants into the UK has been disrupted following coordinated arrests across Britain and Europe. National Crime Agency officers arrested three people on Monday as part of a coordinated operation with French police against a people-smuggling organised crime group involved in transporting Vietnamese migrants to the UK in lorries and small boats.

NCA officers arrested a 25-year-old woman at an address in Wrexham, Wales, and a 25-year-old man was arrested in Newcastle-upon-Tyne on the morning of March 30. The woman arrested on Monday is suspected of assisting that group by laundering money, while the man is believed to have organised facilitation through lower members of the crime group.

Another 26-year-old man was arrested in Birmingham after a warrant for his arrest was issued by French authorities.

He is suspected of overseeing accommodation for migrants destined for the UK. The National Crime Agency said he was remanded into custody as the process to extradite him to France begins, and was due to appear at Westminster Magistrates’ Court on Monday.

French Police arrested another 16 people in and around Paris in simultaneous raids, supported by colleagues from Europol, Eurojust and Belgian federal police. They also discovered 41 migrants, including 11 who were staying in one address.

The arrests were connected to the same investigation, which saw five men apprehended and charged in north west England and South Yorkshire in February this year.

Investigators believe the network arranged journeys for migrants from Vietnam into central and eastern Europe via commercial flights, before moving them onwards to France. From there, individuals were transported to the UK using small boats across the Channel and concealed within lorries. The crime group is also suspected of holding migrants’ genuine passports as a form of control, effectively trapping them in debt bondage.

According to Europol, the network arranged more than 200 crossings from France to the United Kingdom, transporting over 1,000 migrants across the English Channel and generating an estimated €50 million (around £43 million) in turnover. Financial investigators also traced roughly €1.6 million (£1.4 million) in transfers sent from the UK back to Vietnam.

Migrants were charged up to €50,000 (£43,643) for the full journey from Vietnam to Britain. For the final leg from France to the UK, individuals paid between £8,000 and £10,000. These fees were part of a wider package that included visa arrangements, flights into Europe, temporary accommodation, and onward transport.

Many were unable to pay the full cost up front. As a result, they arrived in the UK burdened with significant debts, leaving them particularly vulnerable to sexual and labour exploitation, Europol said. Investigators say they were often coerced into exploitative situations to repay their smuggling fees.

Alex Cruise, NCA senior investigating officer, said: “These arrests are a great example of partnership working with our colleagues in France to tackle the groups behind dangerous crossings to the UK. Such journeys put those being moved at great risk and undermine border security.

“Tackling people smuggling remains a top priority for the NCA, and this is one of approximately 100 ongoing investigations targeting groups or individuals both directly involved in organising journeys, or those who facilitate that criminality.

“Our investigation continues with the evidence we have gathered today.”

Minister for Border Security and Asylum, Alex Norris, said: “This government is bearing down on those who attempt to abuse our borders.

“These arrests demonstrate the strength of our cooperation with France in confronting the criminal networks behind the unacceptable Channel crossings which threaten our border security.

“We are strengthening law enforcement powers so officers can intercept, detain and arrest people smugglers faster to restore order and control to our borders.”
