Cătălin and Mihaela Didilă, aged 44 and 41, were both detained at their home in Spaines Road, Huddersfield, last Tuesday, July 6, as part of a week-long joint operation involving the National Crime Agency's International Crime Bureau and the police National Extradition Unit (NEU).
The week of activity was carried out in conjunction with partners at Interpol.
It saw NCA and NEU officers work together to track down a number individuals wanted for modern slavery, human trafficking and people smuggling offences in locations across the country.
The couple are wanted in Romania, where they are alleged to have been involved in an organised crime group involved in trafficking women and money laundering. In one case they are suspected of tricking a 17-year-old girl to come to the UK, where she was eventually forced into prostitution.
The following day, a warrant was executed on Calvert Lane in Hull to arrest Lithuanian national Tomas Žemrieta, 37.
He absconded from custody in Lithuania in 2019 after being jailed for four years for being part of an organised crime group who recruited people in Lithuania and trafficked them to the UK for the purposes of labour exploitation.
Further arrests also took place in Lincoln and Wolverhampton and Coventry.
All those detained have now appeared before Westminster Magistrates Court and are the subject of extradition proceedings.
Head of the NCA’s UK International Crime Bureau, Kathryn Clarke, said: “This operation has seen the NCA work closely with Interpol and police colleagues at the National Extradition Unit to identify, track down and arrest six people wanted for serious offences overseas, living here in the UK.
“They thought they were out of reach but they were wrong, and as result of these arrests the British public are safer.
“But there is an important message to send out here and that is that the UK is not a safe haven for overseas fugitives or people involved in trans-national organised crime.
“We are determined to make sure wanted criminals spend their lives looking over their shoulder, knowing we are actively seeking to arrest them and return them to face justice.”
