Two women threatened to cry rape unless a Luton taxi driver handed over his takings, a court has heard.
Carlie Clark, 19, and Selina Dunning were convicted of robbing taxi driver Muhummed Laqib after he picked them up in Welwyn Garden City, Herts.
The Driver, who works for Anglia cars, told jurors how Dunning warned him: "Whatever your takings are tonight you are going to give them to me or I am going to make a noise you raped me."
When Mr Laqib replied "Go on then", Clark, who was sitting in the back of the cab, tried to strangle him with a belt, while Dunning went through his pockets.
But the taxi driver of seven years managed to get free, grabbed his takings, and ran up the road and after being further attacked and chased by both girls managed to struggle free.
