According to the son of the All Progressives Congress (APC) candidate in the November 21, 2015, governorship election, Audu died of ulcer. Audu died on November 22, 2015 shortly after the Independent National Electoral Commission (INEC) declared the elections inconclusive.
Speaking with The Sun, Mohammed said his father died of ulcer and not spiritual attack as was widely reported in the media. He said: “We didn’t grow up to believe in any spiritual attack. More so, I know that he died of bleeding peptic ulcer. I knew he was under pressure, I knew a lot of things went wrong at the time, but then, as for the election, he was coasting home to victory.
