Police are appealing for witnesses after a woman was subjected to false imprisonment in Warrington, North Buckinghamshire.
The incident occurred at around 2pm on Friday (21/6) on the A428 layby near to the BP garage in the hamlet of Warrington just north of Olney.
The victim was in the layby when the offender got out of his car and threatened her with a knife and made her move over to the passenger seat.
The victim moved over and the offender got into the car, making threats to kill her over a period of six hours, and also demanded money from her.
The offender told the victim that he had a gun.
He is described as a black man with long dreadlocks and of a slim build.
The offender’s vehicle is described as a black Saab with a partial registration number of LG54.
Investigating officer Detective Constable Susan Russell of the Domestic Abuse Investigation Unit based at Bletchley, said: “This was a frightening incident for the victim, who despite her ordeal, was not injured.
“It is believed the victim and the offender are known to each other, and this is an isolated incident and there is no wider risk to the local community.
“This incident happened on a busy stretch of road, and I am appealing to anybody who believes they witnessed anything, to contact the 24-hour non-emergency number 101, quoting reference number 43190188502.
“I am particularly keen to hear from anybody who may have dash-cam footage from around that time, and so I am asking to please check your dash-cams, and contact police if it has captured anything.
