The Nigeria Police Force has released human rights activist and Amnesty International designated Prisoner of Conscience, Omoyele Sowore.
The police had on Monday illegally arrested Sowore and a journalist with the African Independent Television (AIT), Dickson Iroegbu at the Federal High Court, Abuja.
The activist was there to observe the trials of Nnamdi Kanu, leader of the Indigenous People of Biafra (IPOB) and the case involving five #BuhariMustGo protesters arrested at Dunamis International Gospel Centre, Abuja by the Department of State Services (DSS).
SaharaReporters gathered that the activist was brutalised during his arrest and taken to the Federal Secretariat police station.
Sowore was however released after his arrest sparked outrage on social media, with many Nigerians demanding his swift and unconditional release from detention.
The Muhammadu Buhari-led Nigerian government had earlier barred some media organisations from covering the trial of the Kanu.
It also named only 10 media houses approved to cover the trial.
The media organisations include the TV station and newspaper belonging to the national leader of the ruling All Progressives Congress (APC), Bola Tinubu, TVC, and The Nation respectively; Premium Times, Daily Independent, The Herald, NTA, AIT, News Agency of Nigeria, and Channels TV.
