Detectives would like to speak to a woman who was seen getting in a car on Gelderd Road.
Police were called to the junction with Leeds Ring Road, at around 6.15pm on Sunday after reports of a woman, who appeared to be drunk, getting into a man’s car.
The vehicle’s details were taken and officers traced the car.
A 48-year-old has been arrested in connection with the incident and is currently in custody.
The woman was described as white, slim, aged in her late-teens to early twenties, about 5ft 6ins tall, with shoulder-length brown hair.
She was wearing a white vest top, a blue, orange and red ‘Aztec’ skirt and one black slip-on shoe.
A police spokesman said it has been suggested the woman was later dropped off in the Farnley area.
