NNamdi Kanu in prison in Nigeria

NNamdi Kanu, a separatist from Nigeria, is in prison in Nigeria. But how did he get there? He was in exile.

His family say that Kenya's secret police seized him and tortured him, then handed him to Nigeria with no hearing.

I have no opinion about the separatist cause he advocates; I don't support separatist causes by default. However, torture is an injustice, and handing a prisoner to another country without a hearing is an injustice.
