Over 30 people have been arrested as part of a major investigation into the sexual exploitation of children and young people in Northern Ireland.
The inquiry follows a Police Service of Northern Ireland review of cases where young people have gone missing from the care system over the last 18 months.
A total of 22 young people, aged between 13 and 18, may be at risk.
A number of men have already appeared in court charged with sex exploitation and other offences.
Most of the children were abused when they went missing from care homes.
The issue is to be discussed at the Stormont Assembly.
Health Minister Edwin Poots and Justice Minister David Ford are due to attend a committee meeting.
