Members of the Islamic Movement in Nigeria, IMN, on Wednesday took to the streets in the Federal Capital Territory FCT demanding the release of their leader, Ibraheem El-Zakzaky, and his wife.
They have been in detention since December 2015, despite a court order for their release.
The members, who were not in their usual black attires, marched in separate male and female columns by the roadside along Wuse Market in Abuja as they chanted: “Mr. President, Free Our Leader! Obey Court Order!! Where is your Justice!!!”
Mr. Zakzaky and his wife were arrested on December 14, 2015, following a clash between members of his group and the Nigerian Army in Zaria, Kaduna State.
At least 347 members of the group were killed with the army saying they blocked a major road and prevented the army chief, Tukur Buratai, from passing.
The killings have been condemned by local and international rights groups and nobody has been prosecuted for them.
After months in detention without being charged to court, Mr. El-Zakzaky approached the court to demand the release of himself and his wife.
An Abuja High Court presided over by Justice Gabriel Kolawole on December 2 last year said their detention was unlawful and illegal.
The court ordered the Nigerian government to release the detainees within 45 days of the judgement and to pay each of them N50 million as compensation.
The government, however, ignored the order and Mr. El-Zakzaky and his wife have remained in the custody of the SSS.
The Federal Government later gave public interest and security concerns as the major reasons why it has refused to comply with the court order for the release of the detainees.
