DETECTIVES are trying to trace people who tried to help a suspected kidnap victim when she called out for help from a car.
Police say the woman's ordeal is believed to have started in Hertfordshire at about 6pm on Friday, November 16.
The woman, in her 20s and of Asian appearance, was forced into a car by a man in Stevenage.
The blue BMW was then driven to Nottingham.
Detectives say the victim told them that she was able to call for help from the car somewhere in Notts.
Passers-by went up to the car but the alleged kidnapper is said to have told them everything was OK and they left. Hertfordshire officers now want to speak to these people in an attempt to solve the case.
DC Emma Landucci, of Hertfordshire Constabulary, said: "It was described as an industrial-type area and the passers-by were wearing uniforms or overalls.
"The information they have may be vital to our investigation."
The woman was later driven back to Stevenage unharmed. Her ordeal ended at about 10pm that night.
DC Landucci added: "The car was parked in a car park in an industrial area, next to a building or factory.
"It is believed two white men in their 30s and wearing some sort of blue uniform came over to the car to ask if everything was all right, however the male reassured them and they left."
Anyone with information about the incident should contact DC Emma Landucci at Hertfordshire Constabulary on the non-emergency number 101, or call Crimestoppers, anonymously, on 0800 555111.
