The six Federal Road Safety Corps (FRSC) officials who were recently released from their abductors have said that no security agency rescued them.
They said that each of them paid N6m to the kidnappers before they were freed.
Police spokesman Ramham Nansel said no ramson was paid for their release.
But the officials, who spoke on condition of anonymity to BBC Hausa Service, said the police lied.
One of them said, “What the police are saying is a big lie, there is no element of truth in it, the kidnappers established contact with our relatives, the money was withdrawn in Nasarawa town.
