In a statement signed together with County Commissioner Ramadhan Mwabudzo, the two co-chairs of the County Security Committee said the confrontation amounted to organised criminal conduct that would be met with the full force of the law.
"Those who imagine that criminal acts committed in public can be concealed behind anonymity are mistaken," the statement read, adding that investigators were securing digital material circulating on social media to support further prosecutions.
The Sunday confrontation, which pitted two organised groups of youth against each other, left two young men dead. It also destroyed property, including a motor vehicle and no fewer than nine motorcycles, shattering the peace of the neighbourhood.
Eight suspects arrested in connection with the violence were set to be arraigned in court on Monday, the county said.
The Governor reserved his sharpest words for those who bankroll and coordinate the violence, warning that they were neither invisible nor untouchable. "He who rides a tiger eventually discovers that the greatest danger lies not in mounting it but in trying to dismount," he said, adding that their time was coming.
He framed the bloodshed as a betrayal of the county's economic ambitions, describing nights spent negotiating with investors to create jobs, only for some young people to be "bought for a pittance to burn, intimidate, and destroy" the very future being built for them.
The statement also carried a pointed message to political players ahead of a charged season, cautioning that political competition must never become a licence to sponsor violence or recruit young people into criminal networks. Anyone found financing, organising or facilitating such acts, directly or indirectly, would face the full weight of the law.
Sunday's arrests form part of a wider operation approved by the County Security Committee, under which more than 200 suspects have been apprehended across Kisumu.
Those operations, the county said, will continue until criminal networks are dismantled and public confidence in security is fully restored. Citizen Digital
