“By God’s Grace, I will ensure that all the culprits responsible for this barbaric act are swiftly brought to justice. This nonsensical act of raping must stop in Nigeria.”
He extended his condolences to the family and friends of the victim.
Folarin, the Chairman, Senate Committee on Local Content, said he had directed his team to pay a condolence visit in Ibadan.
He said he would personally visit them upon arrival from Abuja.
Folarin disclosed that he was “reaching out to the top echelons of Nigeria’s security agencies”.
