The Federal High Court on Wednesday in Abuja granted Federal Government an interim injunction proscribing activities of the Indigenous People of Biafra (IPOB).
The Chief Judge of the Federal High Court, Justice Abdul Kafarati, granted the injunction in chambers.
The Minister of Justice, Mr Abubakar Malami, had filed an exparte application urging the court to grant the injunction.
President Muhammadu Buhari had earlier given written approval for the proscription of the group, pending legal process.
Governors of the Southeast states took the first step to ban the activities of the group after the military had declared it a militant terrorist group.
