A Portsmouth man and a Hayling Island man were arrested in connection with illegally employing migrants.
A 40-year-old man was arrested on suspicion of fraud and the unlicensed supply of staff, at a private Portsmouth address yesterday after it was raided by police.
The house was one of five to be targeted as part of the Gangmasters Licensing Authority’s crackdown.
Offices in Portsmouth and Havant were also raided and a 44-year-old Hayling Island man was arrested at the Havant office.
The investigation aimed to dismantle an organised crime operation which has been controlling and using migrant workers illegally employed in farms and agricultural nurseries in West Sussex.
Two other private addresses – one in Tangmere and one in Bognor Regis – were raided and a further two people were arrested.
Officers and GLA staff visited six West Sussex nurseries – two in Ferring, one in Chidham, Walberton, Angmering and Funtington – to talk to managers and workers about their experiences.
No arrests were made there.
