Derby human trafficking: Four admit their part in operation
Four people have admitted their part in a human trafficking operation in Derby.
Igor Marcin, 36, and Marek Marcin, 40, pleaded guilty at Derby Crown Court to human trafficking into and within the UK.
Dagmar Marcinova, aged 38, pleaded guilty to fraud and theft while Gabriela Marcinova, 42, admitted fraud.
The group were arrested in 15 July following a series of raids across Derby. They will be sentenced next month.
During the raids last year Derbyshire Police and officers from the Serious Organised Crime Agency's human trafficking centre found 11 men who had been trafficked.
The victims were taken to a special reception centre set up by Derbyshire County Council, Derby City Council, the Salvation Army and the Red Cross.
Charges against two other people arrested as part of the inquiry have been dropped.
