It has been reported that Codo, who owns Transport and Port Management System Limited, died on Thursday due to lack of proper medical attention.
Codo, a businessman from the Republic of Benin, and is being investigated for alleged €29m fraud by the Economic and Financial Crimes Commission.
Codo was granted bail in November 2019 but could not fulfil the bail conditions and despite appeals to have him released on compassionate ground due to COVID-19 outbreak, the Nigerian authorities refused until he died in custody.
According to reports, Jean Codo was said to have collapsed in prison and rushed to the military hospital in Lagos where he died on Thursday morning.
Like Codo, a suspected cross-border robbery kingpin, Hamani Tijani, died at the Kirikiri Maximum Prisons in January 2014 after suffering partial stroke for nine months.
Spokesperson for the Nigerian Prisons Service, Lagos Command at the time, DSP Biyi Jeje, confirmed the development to journalists.
Jeje said 42-year-old Tijani died in the clinic of the maximum prison.
A citizen of Niger Republic, Tijani was arrested in 2003 in Benin Republic and spent 11 years in prison while facing trial before his death at Kirikiri.
