Osogbo—The chairman of the Coroner’s Inquest set up by the State Governor, Mr Rauf Aregbesola, to uncover the circumstances surrounding the death of Senator Isiaka Adeleke, Chief Magistrate Olusegun Ayilara, went tough yesterday as he threatened to issue a bench warrant against the Divisional Police Officer DPO, of Dugbe Police station, Osogbo and the Officer in charge of Homicide, for shunning the sitting and refusal to testify before it.
