Activist Deji Adeyanju granted bail after 67 days in detention
Mr Adeyanju was arrested on December 13 over allegations he was involved in a murder in Kano in 2005.
The police did not formally arraign Mr Adeyanju for the alleged murder.
PREMIUM TIMES confirmed Mr Adeyanju was charged for murder in 2005 at the Kano State High Court, but was discharged and acquitted in 2009 after a lengthy trial.
The previous acquittal and police’s failure to arraign Mr Adeyanju for several weeks after arresting him fueled speculation that his detention was politically motivated. The police denied the allegations.
