"We have names of people whom we suspect are behind these clashes. Some of them are from the neighbouring county of Kisii, others are from both clans. We have their names and they should report to the nearest police station," he added.
The renewed clashes happened two days after more than 30 elders met the county commissioner and Narok Governor Samuel Tunai and agreed to bury the hatchet.
Last month, several people suffered arrow wounds, with three more sustaining gunshot wounds in a fight over the same piece of land.
During the clashes, four people including two chiefs and their assistants from Nkararo and Enoosaen locations were arrested over links to the boundary dispute.
Mr Kimiti later held a meeting with both sides in his office on Friday and warned them that demarcation of a boundary is a technical issue which should be left to qualified officers.
"The Siria and the Iriausi Ngishu border has been a hotspot for conflict for a long time. It has brewed hatred among the two clans and the government is in the process of making sure it will not happen again," said Mr Kimiti.
During the meeting, it was agreed that land adjudication officials and the county land registrar should identify the boundaries and erect beacons in the presence of eight local leaders, four 4 from each side.
Politicians were cautioned to keep off the boundary matters as Mr Tunai indicated that it was not a political process.
During the meeting the two groups resolved that the timeline for implementing their resolutions will be two weeks and that the governor and the county commissioner will be responsible for implementing the resolutions.
