Two brothers in Britain who tortured two boys in a sadistic attack have been sentenced to an indefinite period of detention.
Sheffield Crown Court heard how the pair, then aged 10 and 11, threatened to kill their nine-year-old and 11-year-old victims in Edlington.
The judge said the boys used violence and sexual degradation to dominate their victims during the 90-minute ordeal in April 2009.
The brothers will serve a minimum jail term of five years and have been placed on the sex offenders register for three years.
After sentencing, Doncaster Council's director of children's services offered a profuse apology to the victims for deficiencies which left the brothers free to attack.
The court earlier heard the brothers, who were placed in foster care a few months before the attack, had a chaotic upbringing with their violent father, mother and five brothers.
