A woman was sexually assaulted after getting into a car she thought was a taxi following a night out.

The woman and her female companion were also sexually harassed by the man driving the car and his male passenger.

Police have launched an investigation into the attack, which took place in Jedburgh in the Borders in the early hours of Sunday.

Officers said the women had been at a function in the town, which finished around midnight.

They then got into a small, dark-coloured four-door car which they thought was a taxi.

The two men made sexual remarks during the journey and one of the women was sexually assaulted.

The women got out of the car and were left at the roadside outside of town, before being given a lift home by a couple.

Police are trying to trace the dark car, which had a noisy exhaust, and also wish to speak to the couple who gave the victims a lift.

Inspector Alistair Hutchens said: "We would like to speak to anyone who was in the area of Jedburgh Town Hall around midnight on Saturday evening/Sunday morning or who has any information about these two men purporting to be operating a taxi.

"We are particularly keen to speak to the couple who assisted the young women and gave them a lift to an area near Oxnam, Jedburgh.

"Anyone who saw a small dark coloured vehicle with a noisy exhaust driving around Jedburgh, offering people lifts, is also asked to get in touch."

Anyone with information has been asked to contact officers on 101 or anonymously via Crimestoppers on 0800 555 111.
