Police have arrested the killers of Pa Defwan Dariye, the father of former governor of Plateau State, Joshua Dariye.
The abductors killed the 93-year-old after they had collected N10 million ransom from his family.
The police paraded the leader of the kidnap gang, Jethro Nguyen, at the Force headquarters, Abuja, on Wednesday.
Nguyen, 53, an indigene of Bokos, confessed that he gave a gang member the order to shoot Pa Dariye.
He said he hired 10 others including some Fulani herders to abduct the old man from his palace, adding that he was kept at their hideout for about 10 days before he was murdered.
He said they abducted the deceased "because he was a good target to make money as his son was a one-time governor of Plateau State and senator of the Federal Republic."
