Mr Adeyanju’s arrest on December 13 on allegations of murder has drawn nationwide attention.
The arrest itself came after the activist had spent a week in prison between late November and early December 2018. He was leading a protest against alleged police bias ahead of the general elections when he was arrested and accused of defamation against senior security chiefs.
His December 13 arrest was linked to a homicide case that was concluded in 2009.
Although Mr Adeyanju was named in the murder trial, he was discharged and acquitted after four years of prosecution in 2009.
