Rashid Harif, 24, was under a slavery and trafficking order when the missing girls, aged 14 and 15, were discovered in his flat.
The order specifically prohibited Harif from contacting and being in the presence of any child under 18, unless unavoidable as part of reasonable daily life.
Officers tracked the girls’ phones to Harif’s address after they were reported missing.
Harif, of Dover Road, Walton, pleaded guilty to committing an act prohibited by trafficking or slavery and breaching his order. He was sentenced to 10 months in prison at Cambridge Crown Court on Monday (June 6).
PC Lauren Easton, who investigated, said: “Harif has proved he is not able to stick to the conditions of his order and I am glad justice has been done.”
