Two men are due to face magistrates next month charged in connection with human trafficking in Medway.
It follows a multi-agency investigation in 2013 into the alleged exploitation of Slovakian nationals, living and working in the Medway Towns.
The victims were working in a number of different industries, including the food industry.
Marian Dzuga, 36, of Windsor Road in Gillingham, was charged with four counts of knowingly requiring another person to perform forced/compulsory labour, one count of arranging or facilitating travel of a person within the UK for exploitation and one count of trafficking a person into the UK for exploitation.
Jozef Dzuga, 35, of Salisbury Road in Chatham, was charged with trafficking a person into the UK for exploitation.
Both men have been bailed to appear at Medway Magistratesâ€™ Court on 10 February.
