A rapist was caught by his DNA after he took the wrong condom from the scene of the attack.
Dawood Mohammed, 26, raped a prostitute in a beer garden twice before picking up a condom and leaving the scene.
He then destroyed it thinking he had got rid of the evidence.
But forensics later proved that he had taken someone else’s discarded condom, leaving the one he had used at the Harp of Erin in Bradford, West Yorkshire.
Bradford Crown Court heard that Mohammed had previously paid for sex with his victim but this time there was a confrontation.
He told her not to scream and then raped her twice.
Judge David Hatton told Mohammed he had forced the woman against her will to have sex, and added: ‘The nature of that woman’s work does not affect, one jot, the seriousness of your offending, nor the inevitable trauma that she will have suffered.’
He had pleaded guilty earlier this year to two charges of rape. He was initially deemed unfit to plead because of mental health issues, and found guilty after a trial in January 2015.
On February 12 this year, Mohammed was deemed fit to give pleas to the charges and he has been in custody ever since, the court was told.
Fiona Clancy, for Mohammed, said her client had previously suffered from acute paranoid schizophrenia.
She said: ‘Consider his mental health as a mitigating factor, but in no way an excuse. He was suffering from distorted thought and behavioural patterns at the time.’
Judge Hatton gave Mohammed seven years in prison for each charge, to run concurrently.
