A man suspected of being a significant supplier of small boats equipment to people smugglers has been arrested in Amsterdam following a joint operation by the UK's National Crime Agency (NCA) and Dutch and Belgian police.
The man is alleged to have supplied engines and boats to smugglers in northern France, according to the NCA.
The Turkish national, 44, was arrested at Schiphol Airport on Wednesday and will be extradited to Belgium to face charges of human smuggling.
NCA director general for operations Rob Jones called the arrest a milestone in one of the agency's "most significant investigations into organised immigration crime".
