A teenager trapped a six-year-old girl in a room and brutally raped her.
Aaron Abbott, now aged 23, was 16 at the time he carried out the attack on the youngster.
Abbott, of Sawley Close, Eastmoor, was jailed for nine years after being found guilty of rape.
The trial at Leeds Crown Court heard how Abbott blocked the door of the room with a wardrobe and stifled the girl’s screams for help.
Afterwards he told the young victim that he would do the same thing to her again if she ever told anyone.
The offence happened at a time when Abbott and the girl were both in care.
Judge Sally Cahill, QC, said: “I am perfectly satisfied from the evidence I have heard...she was isolated and was not being given the care that one would hope by the adults.”
Sentencing, the judge said: “She was isolated and had no one to turn to when she was assaulted by you.”
The court heard the victim is still struggling to come to terms with what happened.
Matthew Harding, mitigating, said Abbott was only a child himself when he committed the offence. He described that attack as an isolated incident which had never been repeated.
Det Insp Lawrence Bone, of West Yorkshire Police, said: “Abbott put the victim through an appallingly traumatic ordeal which deeply affected her for many years before she felt able to tell anyone about what he had done.”
