Four human rights defenders (HRDs), Moussa Tchangari, Ali Idrissa, Nouhou Arzika and Lirwana Abdourahmane were among a group of people arrested and detained on 25 March by security forces in Niamey, Niger. They have been charged with ‘organisation and participation in a prohibited demonstration’, ‘complicity in violence’, ‘assault’ and ‘destruction’ in connection with a peaceful protest organised by their organisations, but which they did not attend.
