A Bournemouth woman has been sentenced to 15 months in prison after pleading guilty to perverting the course of justice.
Cheryl Moss, 26, falsely claimed that a 19-year-old man raped her along an alleyway near St Peter's Road in Bournemouth during the early hours of November 7 2009.
She was sentenced at Bournemouth Crown Court.
Moss, a mother of four, had been with the man during the evening and CCTV footage showed that her actions were consensual.
Despite being shown this evidence, Moss maintained that her allegations were true.
Detective Inspector Steve Thorpe, of Dorset Police's Public Protection Unit, said: "Whenever Dorset Police investigates any report of rape, the victim's care is of paramount importance.
"We work tirelessly to thoroughly investigate such reports and we are determined to bring offenders to justice.
"Equally, we also take false accusations very seriously and Cheryl Moss has suffered the consequences of her malicious report.
"Her actions not only caused detectives to spend valuable time and resources investigating this incident, but, more importantly, caused entirely unnecessary distress to the man she accused."Julia Woodward, Senior Crown Prosecutor, added: "This case went to court because Cheryl Moss continued with her claim despite the incontrovertible evidence that proved she had not been raped.
