Kanu's family alleged that the prisons authorities and the officials of the Department of State Service (DSS) are humiliating the Biafra leader and other Biafra agitators detained with him in Kuje prison.
Mr. Emmanuel Kanu, Nnamdi Kanu's brother, on behalf of the family, made this known in a statement issued in Awka, Anambra state.
The family also accused the Federal Government of plotting to kill Kanu.
They also said that the IPOB leader and other IPOB detainees in detention have been stopped from receiving visitors.
The family also petitioned Amnesty International and Human rights Watch.
The petition reads in part: "We observed with great dismay the conspiracy by the DSS and the Prison authorities through their prison wardens to stop Mazi Nnamdi Kanu from receiving visitors in Kuje prison Abuja.
"The leader of the indigenous people of Biafra Mazi Nnamdi Kanu and others detained illegally alongside with him were only allowed to receive visitors for one hour a day from Monday to Friday in a week while other inmates were always allowed to receive visitors five hours in a day from Monday to Sunday, seven days a week.
"It is a huge embarrassment on the side of the British government who have been denied access to visit Mazi Nnamdi Kanu in Kuje prison by the security agents and prison authorities through the prison wardens.
"The security agents and prison wardens stopped the British people who intended to visit Mazi Nnamdi Kanu in the prison to see the leader of the indigenous people of Biafra IPOB."
They alleged that Kanu was denied the chance to receive visitors as part of the plan to discreetly kill him.
The petition further reads: "Nevertheless, we observed that the security agents and prison authorities through the prison wardens are planning to eliminate Mazi Nnamdi Kanu without anybody knowing when it will happen, that is why they are making sure nobody visits him again.
"In line with this, we are calling on international community, USA, EU, Amnesty International, Human right Watch, Men and Women of good conscience and other relevant Human right organisations around the globe to caution the federal government of Nigeria and her security agents to stop their barbaric attitude towards my brother, Mazi Nnamdi Kanu."
