"Forty-one of the suspects are to be charged with terrorism and culpable homicide, which are punishable by death," police spokesman Emmanuel Ojukwu said.
The remaining detainees would be charged with unlawful possession of firearms, rioting and "mischief by fire" for the burning of buildings during the attacks.
