Maadai Dan-Tsoho, the principal witness in suit against Abdul-Aziz Nyako, son of the impeached governor of Adamawa State, Murtala Nyako, is dead. He died of asthma attack on Tuesday in Yola, Adamawa state.

His death might introduce hiccups in the prosecution of the younger Nyako, who was taken to court by the Economic and Financial Crimes Commission.

Mr. Dan-Tsoho testifying against Abdul-Aziz earned him a suspension from his banking position. Mr. Dan-Tsoho came into prominence when he replaced Kashim Shetima, the current Governor of Borno State as the regional manager of Zenith Bank, North Eastern operations. There were allegations of his complicity in sharp practices at the bank.

He was noted for his aggressive investments and had major stakes in the new Azman Airlines, Azman petroleum and a chain of real estate holdings in Abuja, Nigeria’s capital. He was also the owner of Dan Tsoho hotel, a high brow hotel in the Malamre District in Jimeta, Yola.
