A man suspected of being a “major supplier” of boats for people smugglers operating the English Channel migrant crossings has been arrested.

The 44-year-old Turkish man was detained at Schipol Airport in Amsterdam on Wednesday after a joint investigation by Dutch and Belgian authorities and the UK’s National Crime Agency (NCA).

The man is suspected of shipping dinghies and engines from Turkey and storing them in Germany, before they are moved to northern France for crossings, an NCA spokesman said.

The man is facing extradition to Belgium over charges of human smuggling, the spokesman added.

The NCA director general in operations, Rob Jones, said: “We suspect that this individual is a major supplier of boats and engines to the smugglers operating in Belgium and northern France.

“The types of vessels and engines we see used in making these crossings are highly dangerous and completely unfit for open water.

“At least 50 people are known to have died this year as a result. There is no legitimate use for them.”

So far this year more than 32,000 people have arrived in the UK having made the journey across the English Channel by boat, according to Home Office figures.

The operation comes as the NCA is leading around 70 live investigations into organised immigration crime or human trafficking, according to the agency.

The arrest of the suspected boat supplier was carried out through a Europol Operational Task Force and partners.

A spokesperson for the public prosecutor’s office of West-Flanders said international cooperation is “crucial in the fight against human smuggling”.

Home Secretary Yvette Cooper added: “We will relentlessly pursue the criminal smuggling gangs making millions out of small boat crossings that undermine our border security and put lives at risk.

“This major investigation shows how important it is for our crime-fighting agencies to be working hand in glove with our international partners to get results.”
