Policemen have arrested supporters of the leader of the Indigenous People of Biafra, Nnamdi Kanu, at the Federal High Court in Abuja on Monday as his trial resumed.
The supporters had attempted to gain access into the premises of the court where their leader's trial was taking place but failed.
They, however, converged by the side of the road chanting solidarity songs and addressing journalists which angered policemen.
A video from the scene making the rounds on social media showed a police officer asking them to leave the side of the road where they had converged.
An officer was seen in the video chasing one of the supporters with a pistol threatening to shoot.
Another video from the scene showed some arrested IPOB members inside police vans beside the court which was heavily guarded by security operatives.
Kanu's IPOB is seeking the restoration of the defunct Republic of Biafra that went to war with Nigeria from July 6, 1967, to January 15, 1970.
