The Department of State Services has reviewed that veteran actor Chiwetalu Agu, was brought to its custody by the Nigerian Army.
It however, added that justice would be served.
Dr Peter Afunaya, DSS Spokesman made this known during a brief chat with the press on Friday.
Afunaya said, “Army brought him to us. Justice will take its course.”
He, however, refused to answer further questions.
Agu was arrested around Upper Iweke in Onitsha, Anambra Stare on Thursday for wearing a Biafra outfit
The state has witnessed several incidents of violence in the last couple of weeks ahead of the governorship election next month.
Authorities believe separatist groups, notably the Indigenous People of Biafra, are behind the attacks but IPOB denies this.
Agu has been an ardent supporter of the Biafran struggle and had accused the Nigerian government of marginalising Igbos.
