Forensic experts would be engaged in investigating the killings in an apartment discovered in Soka area of Ibadan, the Oyo State Commissioner of Police, Mr. Mohammed Indabawa, said on Monday.
About 20 decomposed bodies and some rescued 16 emaciated captives from an underground dungeon believed to be a ritual killing site on Saturday.
In what has shocked residents of Ibadan, the officers also discovered several decomposing bodies and body parts, hundreds of human skulls, old clothes, photographs and voter cards in the chamber located in a forest near Soka.
Indabawa, who visited the community, said: “I am personally involved in the investigation of this case and whoever is involved shall be apprehended.
“We will leave no stone unturned and I can assure you that investigation has commenced which would involve the services of forensic experts,” he said.
Indabawa denied an allegation that the police failed to take action after being informed of the suspicious activities going on in the apartment, adding: “It would be wrong to say that the police knew about it before now and did nothing.
“You will recall that we responded to the situation immediately we heard of the place from the people.
“I will, therefore, request that if anyone has a vital information, he should come to my office or call me on my personal telephone number 08032002676.
“I will, however, say that people should allow the police to conduct their investigations without interference. Let us all be law abiding in this situation,” he said.
He also advised residents not to act on rumours, saying “rumours break and destroy the nation and the peace of the state and should therefore be avoided.”
