It was unclear whether the attack on the local language Ta'o FM station in Okene town was orchestrated by Nigeria's Boko Haram militants or the powerful organized robbery and kidnapping rings that operate in the West African country.
"Three security guards and an engineer working for the station were killed. We are investigating who could be responsible and why," Shola Adebayo, the public relations officer for state police, told Reuters.Adebayo said police believed Ta'o FM was the target.
While Kogi is a way off from northeastern Nigeria, where Islamist group Boko Haram has waged a six-year insurgency, the region has also experienced intermittent attacks by the militants intent on creating a caliphate in west Africa.
