A statement, released by the GLAA this morning, reveals its investigators were supported by officers from Gwent Police in making the arrests at addresses to the south and east of the city centre this morning.

The suspects, a Latvian man and a Lithuanian man and woman, are in custody and being questioned by the GLAA.

GLAA senior investigating officer Andy Davies said: “We started this investigation after concerns were raised to us by a food processing and packaging company about a temporary worker who had been supplied to them.

“Tackling modern slavery is a priority for us as an organisation, and we will not hesitate to act on intelligence indicating that workers are at risk of exploitation.”
