Yoruba Nation agitator Sunday Adeyemo is reportedly hospitalised in Benin Republic where he is being detained.
One of his lawyers, Yomi Aliyu, disclosed this while speaking with BBC Yoruba on Wednesday.
Mr Aliyu said Mr Adeyemo popularly known as Sunday Igboho is suffering from kidney failure which he developed while being held in the prison of the neighboring country.
Mr Igboho who was declared wanted by the Nigerian Government escaped to Benin alongside his wife en route Germany when he was arrested and arraigned before being remanded in prison.
The State Security Service (SSS) had accused the secessionist of being a gun runner but he denied the accusation.
“Igboho was not diagnosed with this sickness before he was arrested in Cotonou,” Mr Aliyu said. “It was so critical that they had to rush him to the hospital.
“I can’t tell if he has been returned to the prison from the hospital but what I know is, he’s battling ill health and it seems his kidney and lungs are already being affected.
“Even though I cannot tell which part of his body the sickness has really affected, I know it has to do with his internal organs,” he added.
