Police are investigating after reports that a woman was assaulted and held captive by a man as the pair drove along a busy road.
Officers were called shortly before 7.30am on Tuesday morning by a woman reporting an assault.
The call was ended abruptly but the woman was able to provide an approximate location and a description of the car she was travelling in.
It is believed that the vehicle, a silver Audi A4, had travelled from the Radford area along the A60 towards Papplewick, before turning around and travelling back towards Nottingham.
It was pulled over shortly afterwards in Mansfield Road, Daybrook, and a 37-year-old man was arrested on suspicion of assault, false imprisonment, and making threats to kill. He has since been released on bail pending further enquiries.
Detectives are now appealing for any witnesses to come forward and would particularly like to speak to anyone who may have dash-cam footage of the car.
Detective Constable Sean Parker, of Nottinghamshire Police, said: “This was a very serious incident and we are determined to do all we can to investigate what happened. We believe this victim was subjected to a prolonged ordeal – some of which may have been seen by other road users.
“If you saw a silver Audi 4 driving along the A60 in either direction on Tuesday morning we would like to hear from you. You may have seen the vehicle driving erratically or may even have witnessed what looked like an argument between the two people inside. We would be especially keen to view any dash-cam footage you may have.”
Anyone with any information is asked to call 101 quoting incident 137 of 20
