A high court judge in Nigeria has adjourned the terrorism and treason trial of the detained secessionist leader, Nnamdi Kanu, after he was not presented to the court.
The prosecution did not explain the absence of the leader of the banned group Indigenous People of Biafra but his lawyers said they were worried about his safety.
The trial will now start on 21 October.
Earlier, at least seven people were arrested for holding a protest outside the court.
Mr Kanu had been wanted by the authorities since skipping bail and fleeing the country in 2017.
He holds British citizenship and the circumstances of his extradition back to Nigeria last month are unclear.
