Children in care homes are being subjected to sexual abuse of a "violent and sadistic nature", England's Deputy Children's Commissioner Sue Berelowitz has warned.
She made the comments as the Government announced new reforms that aim to better protect youngsters who reside in the country's 455 children's homes.
The report into care home standards was ordered after the jailing of a sex abuse ring in May which preyed on vulnerable girls in Rochdale.
Only one of the girls was in care at the time of the abuse but all were said to have been known to social services at some point in their childhood.
The ongoing inquiry has highlighted evidence that children in care are particularly vulnerable to child sex exploitation, with some residential homes being specifically targeted by abusers.
Children's Minister Tim Loughton has said a new system of measuring how many children go missing each year would be used.
More would be done to ensure that children's homes are properly protected and located as police and local authorities are not currently able to share information about where they are.
More will also be done to make sure children are sent to homes closer to where they are from.
Ministers also want to see the quality and effectiveness of children's homes improving by making inspections tougher.
