The former Governor of Zamfara State (Abdulaziz Yari) was detained by the Economic and Financial Crimes Commission, over alleged illegal financial dealings.
According to some reports, Yari was detained by the anti-graft agency at their office in Sokoto state.
The former Zamfara State Governor was detained by the commission after he had been interrogated for many hours on Tuesday.
A top official of EFCC that spoke on the development noted that Yari would be detained for at least one week because of the enormity of corruption cases against him.
EFCC had earlier questioned the former Governor in February in Lagos State.
