As the director of a United Kingdom-registered radio station named Radio Biafra, Kanu propagated Biafran separatism.[12][13] He was arrested on treason charges in Lagos, Nigeria on 14 October 2015 and was detained for more than a year, despite various court orders that ruled for his release. When in court, Kanu appeared regularly wearing a Jewish prayer shawl and head covering. He said in court, that he "believes in Judaism" and considers himself a Jew. He has led his Biafran people to various Jewish prayers and religious observations on different occasions.[14] On 28 April 2017, Kanu was released from prison on bail.[3] Nigerian security forces attempted to quash IPOB's armed wing, the Eastern Security Network, which culminated in a low-level conflict in early 2021. Despite the fighting, Kanu maintained that IPOB was interested in a peaceful solution and achieving Biafran independence without violence or harm. In June 2021, he was widely reported to have been allegedly re-arrested by Interpol[15][16][17] in Kenya and handed over to Nigeria but in April 2024, Interpol denied any involvement in the arrest and consequent rendition to Nigeria.[18][19]
