A UK woman is facing jail time after falsely accusing two men of rape because one took too long to find his car and drive her home.

Comfort Yinusa, 22, met the men, who cannot be named, at the Dog House nightclub in London in October 2013, The Mirror reports .

When one of the men agreed to give her a lift home, she stayed at a McDonald's while he looked for his car.

After 45 minutes, during which Yinusa reportedly became more and more angry, the man returned to pick her up but Yinusa called her boyfriend, Kenneth Umezie, to take her home instead.

On the way home she told Mr Umezie she had been raped by the man, an accountant originally from Nigeria, and his friend had groped her.

After calling police and filing a complaint, police cordoned off the area and arrested the men, who spent 18 hours in custody.

CCTV footage showed the woman joking with the men and swapping numbers before the man left to look for his car.

She refused a medical examination and to attend further police interviews.

After spending six weeks on bail, the charges were dropped against the two men.

Yinusa, who was drunk and high on cocaine at the time of the rape allegation, was charged with perverting the course of justice in December 2013.

The case reportedly wasted over 100 hours of police time and cost $6000.

After initially pleading not guilty, Yinusa later changed her plea and will be sentenced on Friday.

Her lawyer, Neville Rudston, blamed the false allegation on "an outburst of anger" at having to wait nearly an hour for a lift.

Judge Rook granted Yinusa bail but "did not make any promises" that she will not be sent to jail when he hands down sentencing.
