Alamieyeseigha slipped into a coma two days ago and was placed on life support.
Esueme Dan-Kikili, the Bayelsa state commissioner for information, confirmed that the former governor had died after a cardiac arrest.
According to family sources, Alamieyeseigha suddenly fell ill in his hometown in Ammassoma township of Southern Ijaw local government area of Bayelsa and was rushed to the University of Port Harcourt Teaching Hospital, where he died at age 62.
His remains, according to a source at the UPTH, were later moved to the mortuary in the hospital.
When contacted by The Punch correspondent, the chief medical director, Professor Aaron Ojule, declined to speak on the matter. He directed the newsman to the family of the late former governor.
However, speaking on the tragic incident, Daniel Iworiso-Markson, the chief press secretary to Bayelsa governor, said: “Bayelsa State Government commiserates with his wife, Margret, his immediate family, the Alamieyeseighas, the entire people of the state. The Ijaw nation has indeed lost a rare gem.”
