Benue State Governor Samuel Ortom wants the leadership of Miyetti Allah to be prosecuted.
He believes the herdsmen group has issued enough threats to warrant a day in court.
Ortom talked to journalists after meeting with President Buhari in Abuja.
Meanwhile, the Deputy Inspector-General of Police, Operations, Joshak Habila, has said detectives are zeroing in on the leadership of the Miyetti Allah Cattle Breeders Association of Nigeria over alleged involvement in the Benue killings.
The MACBAN Chairman, Benue State chapter, Garos Gololo, had told the BBC in an interview that the killings were in retaliation for the theft of 1,000 cows by some people in the state.
But the DIG explained that detectives were still gathering information and intelligence at the crime scene, noting that anyone found culpable in the killings would not be spared.
