Amnesty Internation has described the continuous detention of Omoyele Sowore, Olawale Bakare and Agba Jalingo as a shame for Nigeria.
The human rights organisation said both Sowore and Jalingo are prisoners of conscience.
This was contained in a statement signed by the program manager of the organisation Seun Bakare on Wednesday
The Department of State Services (DSS) arrested Sowore and Bakare in August. The government has refused to release him despite several court orders.
Jalingo is a journalist who is currently facing trial for criticizing the Cross River state government.
Amnesty International lashed the government for its continuous human rights violation, particularly against activists and journalists in an attempt to smother dissenting voices.
It urged the government to drop the ludicrous charges against the trio and obey court order.
“We consider Sowore, Jalingo and Bakare to be prisoners of conscience detained solely for exercising their human rights,” the statement read.
“The Nigerian authorities must drop all charges against them and release them immediately and unconditionally.
“Sowore, Jalingo and Bakare’s continued detention is a matter of shame for Nigeria. Their cases show just how far the authorities in Nigeria can go to silence their critics.
“The government of President Muhammadu Buhari needs to stop filing bogus and politically motivated charges against critics, and start listening to what they have to say.
“The flawed charges and sham trials of Sowore, Jalingo and Bakare expose the inadequacies and bizarre manipulation of the Nigerian criminal justice system and an unacceptable contempt for the rule of law and human rights.”
