One month after his release, pro-democracy activist Oumar Sylla, alias Foniké Mengué, has once again been arrested and arbitrarily detained. He was riding a motorbike with a friend to mobilize protesters on 29 September when he was arrested by police officers in plain clothing in Matoto municipality in the Guinean capital, Conakry. He refused to follow the police officers on account that they failed to present an arrest warrant. Nevertheless, they brutally carried out his arrest which resulted in him sustaining injuries to his hand and finger. He has since been held in Conakry prison on fabricated charges. Oumar Sylla is a prisoner of conscience who must be immediately and unconditionally released.
