Addressing the media at Slopes Hotel in Meru town, the lawmaker said the DCC was being used by aspirants to incite locals.
“I’m asking the government to take stern action against the DCC because he is creating tension between residents of Tharaka-Nithi and Meru.
"If it’s about the border row, it will be resolved by the National Land Commission and county government. The border row is not his mandate," said the legislator.
He said the DCC wanted him to end his meeting in the area, which he insisted was in Tharaka-Nithi and not Meru County.
Mr Karithi, while asking locals to coexist peacefully, said Kaboto has been located in Meru County since the colonial era.
“I’m asking residents of Tigania West and Tharaka not to be divided by politicians,” he said.
“I’m asking administrators and other government officials to desist from engaging in divisive politics.”
On Thursday, hell broke loose when Tharaka-Nithi Governor Samuel Ragwa and Senator Kithure Kindiki confronted Meru's Tigania West Deputy County Commissioner (DCC) Alfred Makau over the matter.
Mr Ragwa and Prof Kindiki became angry when Mr Makau snubbed their peace meeting at Miomponi market near the border and proceeded to visit Kaboto market in Tharaka-Nithi.
Governor Ragwa accused the government of declining to resolve the border issue.
