Deji Adeyanju, Convener of Concerned Nigerians, has been released from Police custody.
He was arrested on November 28, 2018 while leading a protest to demand the neutrality of the Police in the forthcoming general election.
Adeyanju was picked up alongside two others by armed policemen stationed in front of the Force Headqaurters in Abuja.
The Police had arraigned him for "criminal defamatory and derogatory conduct against constituent authority and breach of law and order" in relation to "posts on his Facebook page", among other offences.
He was released at about 7pm on Monday and was received by members of human rights groups, one of who told SaharaReporters: "He has been released and he is high spirits, hale and hearty."
