A rapist who picked up a mother on a night out and forced her to perform sexual acts after locking her in the back of his car has been branded a danger to lone women by a judge jailing him for 11 years.

Sajaket Khan, 25, was also warned that he would spend life behind bars if he committed any more sexual offences.

Bradford Crown Court heard he had previous sexual convictions dating back to when he was 14.

Judge Jonathan Durham Hall told him: “You pose the clearest risk of very serious harm to females. You clearly in your personality have a predatory urge which far exceeds any degree of normality. You’re a very serious risk to lone females who you seek to identify, follow and, as it were, trap.”

On the night of April 28, 2012, Khan picked up the woman who had been out with friends in Queensbury.

Prosecuting, David Gordon said: “By her own admission she’s got very drunk on a combination of wine, lager and something called jager bombs.”

The woman told friends she was going to the toilet, but her next memory was of being in Khan’s car being sick out of the door. He started driving, but kept stopping for her to vomit.

“On one occasion he stopped the car and got in to the back seat with his trousers and pants down. The complainant told him about her partner and children and asked him why he was behaving as he was.

“She tried to get out of the car door and found it was locked. She began to panic and the defendant told her to calm down and said he wouldn’t hurt her,” Mr Gordon said.

The 36-year-old victim, who cannot be named, decided to comply “to get the ordeal over with as soon as possible”.

Afterwards he dropped her near a taxi rank in Harrogate Road, Eccleshill, at about 4am and she got home an hour later. Her partner called the police.

On May 5, 2012, Khan, of Stillington House, off Alison Lane, Bolton Woods, Bradford, was arrested and during interview denied the allegations, but a swab taken from the victim contained Khan’s DNA.

He pleaded guilty to two charges of oral rape at a court hearing in June.

Khan’s previous convictions included indecent assault of a female over 16 and indecent exposure with intent to insult a female in 2001.

In October 2004, he was convicted for indecent assault of a female aged 16 or over, indecent assault and indecent exposure with intent to insult, when he tried to expose a woman’s breast by pulling on her top and tried to remove her trousers after following two girls.

In December last year he was convicted of battery and he lost his driving licence in January.

Jailing Khan, Judge Jonathan Durham Hall QC said the case was an aggravated one, further aggravated by previous convictions.

He gave Khan credit for his early guilty plea and sentenced him to concurrent sentences of six years, with a five year extension, for each count.

Khan was made subject to a sexual offences prevention order and ordered to pay a victim surcharge. He must also comply with sexual offenders notification requirements for life.
