A growing number of children are being sexually abused by other children, say charities.
They say their helplines have seen a big increase in calls from young people who are being abused.
Freedom of information figures obtained by the NSPCC say more than 5,000 children were reported to police in England and Wales as abusers over the last three years.
Almost all of those accused of the abuse of other children were boys.
