A woman admitted falsely accusing an ex-partner of rape after she learned that he was having a relationship with another woman, a court heard.
Rachel Harrison, 20, of Bridgecote, Willenhall, Coventry, was sentenced to six months in a young offenders' institution after she pleaded guilty to perverting the course of justice at Coventry Crown Court last Friday.
Harrison voluntarily told police she had lied and, after she was arrested, admitted: "I wished to hurt him because he told me he loved me but then would not stop a relationship with another woman."
Judge Marten Coates told Harrison: "You know how seriously the police take a rape allegation, and the Court of Appeal has made it clear that when a false allegation is made jail must follow.
"In normal circumstances it would be 18 months to send out a powerful message to the community and to people who might be tempted to do what you have done."
The judge said he would impose the minimum sentence, mainly because the man against whom the allegation had been made, appeared at court to ask for leniency for his ex-partner.
Fenella Sheridan, prosecuting, said Harrison contacted Nuneaton police in July this year and told them she had been raped by her former partner.
She said: "The partner spent 10 hours in custody, he became distressed and vehemently denied it, and he said he hadn't recently had sex with her, consensual or otherwise."
Police later learned that the man had two alibis, and eventually Harrison told police she had lied.
Mrs Sheridan said: "She was arrested and during interview said, 'I wished to hurt him because he told me he loved me but then would not stop a relationship with another woman'."
Chris Jones, defending, said: "The injured party is here in court and, notwithstanding what has happened, is supportive of my client. It is an unusual case."
