(Bloomberg) -- The trial of Nnamdi Kanu, head of a secessionist group in Nigeria, was adjourned until Nov. 10, his lawyer said.

The leader of the Indigenous People of Biafra, or IPOB, pleaded not guilty Thursday to seven new charges including belonging to a proscribed group and carrying out acts of terrorism, his lawyer Ifeanyi Ejiofor said by phone from Nigeria’s capital, Abuja. 

Kanu was returned to the custody of the secret police after the hearing, he said.

The IPOB leader, who fled Nigeria in 2017, was forcefully returned to the country in June to continue a treason trial. IPOB maintains it’s a peaceful self-determination movement committed to creating an independent nation in southeastern Nigeria for the Igbo ethnic group.

The government of President Muhammadu Buhari considers IPOB a terrorist movement and accuses it of waging a violent campaign against state personnel and infrastructure.
