The 20-year old is a student at the University of the Highlands and Islands.
She was attacked in the Southern Provincial capital of Nakorn Sri Thammarat in the early house of Saturday.
Police said she was taken by four Thai men who were driving around in a pick-up truck.
It is alleged that they spotted her and dragged her away as she came out of a late night restaurant.
Police said the girl admitted she was drunk and had been deserted by a fellow traveller from South Africa after both had been advised to leave the Nakorn Vientiane Restaurant because of their condition.
The men were reported to have taken her to the balcony of a neighbouring building where they carried out the attack.
