A man who committed an "appallingly nasty" rape on a 12-year-old girl and made her pregnant has been jailed for 11 years.

Ibrar Hussain, 27, dragged the terrified child into his house, locked the door, shut the curtains and pulled her to the floor, a court heard.

The traumatised girl told no-one about her ordeal, and when her pregnancy was discovered at 30 weeks she had to give birth to the baby.

Hussain, a married man with three children, had admitted raping the girl when he appeared at Bradford Crown Court in May.

Hussain, who was living in Redcliffe Street, Keighley, denied the girl's allegation that he threatened her with a knife and the prosecution accepted that to save her giving evidence at a trial.

Mr Justice Andrew Smith, at Leeds Crown Court, sentencing Hussain, told him: "This was an appallingly nasty offence of rape which has had a devastating effect on your victim."

He said Hussain targeted or groomed the girl and the offence was planned.

"You engineered the situation. You used your strength to pull the girl into the house, locked the door, shut the windows and curtains and raped her," he said.

"Your victim was only 12. You made her pregnant. She knew little or nothing about sexual matters and did not understand that she was pregnant. She told nobody about what had happened.

"You know her background and the community she comes from. You know the effect that this will have on her life, the whole of her life."

Prosecutor Mark McKone told the court that the girl was raped in either December 2003 or January 2004 but she told no-one. Her mother noticed a change in her behaviour because she would not leave the family home and she cried a lot.

In July the girl was taken to Airedale Hospital after complaining of feeling ill. She was discovered to be in an advanced stage of pregnancy. It was too late for a termination.

She gave birth, aged 13.

The girl told the police Hussain locked her in his home, put a knife to her throat and pulled her to the floor in the kitchen.

"He was very heavy and she could not breathe properly because she had asthma," said Mr McKone.

He told how the girl screamed but Hussain put his hand over her mouth.

The girl described the attack as lasting up to 20 minutes before Hussain told her to leave.

When interviewed by police Hussain denied the rape but DNA samples were taken from him and the baby.

Mr McKone said that it was thousands of times more likely that Hussain was the baby's father rather than an unknown man.

Jeremy Lindsay, mitigating, said Hussain's guilty plea had spared the girl giving evidence in court.

"He has -- in anybody's view -- destroyed a young girl's life and destroyed his own at the same time," he said.

After the hearing the victim's uncle said her family was serving a sentence as well as Hussain.

He pointed to the traumatic effect of the crime on their close knit community in Keighley.

He said no sentence was long enough for Hussain, but he accepted that the judge had given the maximum he could.

"Life would not have been long enough for us," he said.

He said the girl was receiving counselling and found it difficult to leave the family home.
