The lawyer of a Nigerian separatist leader has confirmed reports that his client, Sunday Igboho, has been detained by the authorities in neighbouring Benin as he prepared to board a flight to Germany.
Mr Igboho, who campaigns for an ethnic Yoruba state in south-west Nigeria, is wanted by the Nigerian police for allegedly stockpiling arms.
His house in Nigeria was raided by the police three weeks ago.
The arrest has not been confirmed by the Nigerian authorities.
