Detentions of dissidents during the 2011–2012 Saudi Arabian protests included well-known activists such as Mohammed Saleh al-Bejadi, who was arrested on 21 March 2011 for his campaigning for the release of political prisoners, and "previously unknown individuals who have become overnight icons of the protest movement in Saudi Arabia", such as Khaled al-Johani, arrested on 11 March 2011 "Day of Rage". In March 2012, Amnesty International estimated the total amount of arrests related to the protests since March 2011 to be "hundreds". It stated that "most have been released without charge", some remained arbitrarily detained, and some were "charged with vague security-related and other offences".
