Police officers in Cambridgeshire have staged a number of early morning raids linked to the suspected exploitation of migrant workers.

Nine arrests have been made in the Wisbech and March areas of Cambridgeshire.

The raids come two weeks after a BBC investigation into the treatment of migrant workers employed to pick leeks in the Fens.
