The Chief Medical Director of the Ladoke Akintola University of Technology Teaching Hospital, Prof. Akeem Lasisi, says an outlawed drug banned by the National Agency for Food and Drug Administration & Control (NAFDAC) was responsible for the death of Senator Isiaka Adeleke.

Adeleke was certified dead on Sunday, April 23, 2017.

He looked in good spirits a day before his death, while attending a function.

Adeleke was also a former Governor of Nigeria's Southwest State of Osun in the early '90s.

He was 62.

Rendering his testimony at the Coroner's inquest set up by the Osun state government to unravel circumstances leading to the sudden death of the Senator, Dr Lasisi relayed that an autopsy was carried out on the remains at the behest of the politician's family.

According to the Doctor, when Adeleke’s corpse was brought to the hospital, he asked for his medical history and was told that someone who was neither a Doctor nor a Nurse, injected the Senator with a cocktail of illicit drugs.

The drugs were administered after the Senator complained of a pain in his leg, said Dr. Lasisi.

Lasisi said the drugs injected into Lasisi's system were: 5 percent of dextrose, intravenous fluid glory set, scalp vein needle, 2 ampoules of analgin, 4 ampoules of 10mg of diazepam, 1 ampoule of pentasozine, 1 ampoule of getamacine and Valium.

The Doctor said the drugs were administered in excess doses, leading to a collapse of Adeleke's reflexes and occlusion of his respiratory system.

“As a medical Doctor of 27 years experience, I have never given 40grams of diazepam. Analgin is also an outlawed drug, I wonder where the so called person got that from”, said Lasisi.

The inquest is ongoing at the time of filing this.

Chief Magistrate Olusegun Ayilara will be cross examining the Divisional Police Officer of Dugbe Police station, Osogbo, the OC Homicide and the chief pathologist who carried out the autopsy on late Sen. Adeleke.
