Members of the Islamic Movement in Nigeria (IMN) clashed with the police at the federal secretariat, Abuja, on Thursday.
The IMN members who clashed with policemen during a protest at the national assembly on Tuesday, returned to the streets of Abuja on Thursday.
Wielding placards and chanting anti-government songs, the protesters demanded the immediate release of Ibrahim el-Zakzaky, their leader.
They had converged on the federal secretariat and marching towards Eagle Square when they were intercepted by armed anti-riot policemen.
A witness told TheCable that trouble started when the police demanded to speak with leaders of the protesters and two men: Nura Marafa and Mujaid Mohammed who came forward were arrested.
