A woman from Milton Keynes has been given a suspended prison sentence after making a false rape allegation, police said.
Nina Crouch, 29, from Mellish Court, Bletchley, pleaded guilty to perverting the course of justice at Huntingdon Crown Court on Tuesday.
Crouch was given a six-month prison sentence, suspended for 12 months, as well as 150 hours of unpaid work and ordered to pay costs of £535.
She told police that she had been raped in July this year.
The suspect - a 28-year-old man - was arrested and detained in police custody for more than eight hours before Crouch admitted the allegation was false.
Detective Constable Darren Street said: "We take every single report of rape very seriously. Each report is dealt with by detectives and other specialist officers who conduct a full investigation at great public expense.
"The investigation of any false or malicious allegation diverts valuable resources away from genuine crimes with genuine victims. We will take action against anyone who reports a false crime and wastes police time."
