At least two people accused of setting on fire sugarcane farms in the Mapashi area, in Transmara West, Narok County, have been arrested.
They are suspected of being part of the larger group causing mayhem along the border.
Dozens of sugarcane farms have already been torched in the last week.
One suspect was arrested as he sought treatment for a bullet wound at Kenyenya Sub-County hospital in Kisii County on Friday.
They have since been taken to Kilgoris Police Station.
They are expected to appear in court on Monday to face incitement to violence and arson charges.
Locals at Mapashi say at least 300 acres of sugar cane farms have been razed in the new cross border skirmishes which have left farmers counting losses.
Some other farms were torched around the Kona Ya Nkare area on Wednesday while more went up in flames near Nyangusu township, a key intercommunal clashes flashpoint.
Solomon Kuntai, a resident, told the Star at least 12 youth from the had been injured in the clashes.
Most of them have since been treated and discharged from different hospitals in Kisii and Transmara.
"I strongly don't think we should be talking of intercommunal conflicts today. What is needed is dialogue if things go wrong so that we don't lose more lives," he told the Star.
The clashes started last Sunday. Peace talks have been going on in Mapashi.
On Sunday, there were heavy patrols by the General Service Unit officers along the border to forestall further violence.
They were seen patrolling areas of Keiyian, Mapashi and Nyangusu.
On Friday, Transmara West Deputy District Commissioner Hassan Nur said they have initiated talks between the border communities to ensure the sporadic fights come to an end.
"We have partnered with our counterparts from the Kisii side to tackle this menace once and for all. We are already narrowing down to the key suspects," he told journalists at Mapashi.
He, however, said the fights should not be seen as renewed intercommunal violence.
"These are isolated incidents and we must deal with them. People are still going on with normal activities elsewhere," said Nur.
