Mad House Naija has reliably learnt that the doctor who allegedly gave the late Isiaka Adeleke drug overdose is suspected to be a quack.
MHN further gathered that he has since been arrested and investigations are ongoing.
The deceased family is expected to address the press on the latest development soon.
Meanwhile, there had been reports that the deceased was killed because of his interest in the 2018 governorship election in Osun.
Hours after he died, aggrieved youth attacked journalists who visited his residence.
The violence continued on Monday, as youth threatened to bar officials of the Osun government from the burial.
It took the intervention of the police before Idiat Babalola, a senior special adviser to Rauf Aregbesola, governor of Osun state, was rescued.
A mob had descended on her at Adeleke’s residence.
Adeleke was the first civilian governor of Osun.
