The sit-in aimed to advocate for economic reforms, improved income levels, simplification of government procedures, and the fight against corruption. Despite adhering to laws limiting gatherings to fewer than ten people, Saud Al-Mardouf Al-Kathiri was arrested within hours by the Internal Security Service and taken to an undisclosed location without any communication with his family or legal representation. The security authorities did not announce the place of their detention or the nature of the charges against them, leaving them completely cut off from the outside world.
