Saudi sports authorities shut down a female fitness centre in Riyadh on Friday over a contentious promotional video that appeared to show a woman in figure-hugging workout attire.
"We are not going to tolerate this," Saudi sports authority chief Turki Al Shaikh tweeted as he ordered that the centre’s licence be withdrawn.
Al Shaikh, an adviser to Crown Prince Mohammad bin Salman, also told authorities to investigate and prosecute those behind the video.
The video, which was widely circulated on social media but could not be independently verified by AFP, showed a woman with uncovered hair in what appeared to be a gym and kicking a punching bag.
The General Sports Authority said the video contained scenes that could corrupt public morals.
Saud Al Qah’tani, a media adviser to the royal court, lauded the sports authority's swift response, saying on Twitter that the kingdom was on the path of "moderation without moral breakdown".
Last July, police questioned a woman after she appeared in a series of videos, initially posted on Snapchat, wearing a crop top and a high-waist miniskirt.
