Ms Aruyo was one of several witnesses giving evidence to the Commons home affairs select committee's probe into immigration control, specifically about the issue of private fostering.
In written evidence submitted before the hearing, her organisation reported: "We have reports of cases involving Ugandan girls who have been trafficked purposely for council housing.
"They are brought in unaccompanied so they can go into local authority care, they are then impregnated to enable them to become eligible for council flats. The men then disappear and return once the housing problem is solved."
