Saudi authorities are investigating footage of a woman in a miniskirt and crop top walking through a historic site in the ultraconservative kingdom posted to social media over the weekend, reports AFP from Riyadh.

A series of videos, initially posted to the Snapchat account of “Model Khulood”, show a young woman in a high-waisted miniskirt walking through a fort in Ushaiqer, outside the capital Riyadh, playing with sand in the dunes and turning towards the camera for a close-up, her long hair uncovered.

The videos have since been uploaded to YouTube and tweeted by different users.

The local government of Riyadh has issued a memo saying authorities were taking the “necessary measures” to find the woman, who it accused of “walking around... in indecent clothing”.

The Commission of the Promotion of Virtue and the Prevention of Vice—Saudi Arabia’s “morality police”—on Sunday also confirmed it was investigating the case in coordination with “relevant authorities” via Twitter.
