Police on Friday afternoon lobbed teargas canisters at supporters of PNU and ODM candidates who had clashed at two separate venues turning Isiolo town into a political battlefield.
The fracas left at least three people injured and disrupted business in the usually busy town as traders hurriedly closed their premises to ward off looters.
Police in riot gear dispersed the warring groups who had regrouped and started pelting them with stones.
The rowdy youths who were threatening to storm the district headquarters engaged police in running battles for several hours before they were finally overpowered.
Trouble started when ODM supporters met PNU youths who were holding a meeting at Wabera primary school, and had differed over an undisclosed issue before leaving the venue.
Their plea to continue with the meeting fell on deaf ears as Isiolo OCS Mr Erustus Gitari stood his ground that no groups deemed hostile to peace and security could be allowed to conduct meetings.
Isiolo OCPD Mr Chrispin Makhanu said police were on the lookout for trouble makers and warned that stern action will be taken against anybody engaging in acts of lawlessness.
Elsewhere a man was seriously injured while others escaped with minor injuries when supporters of opposing candidates clashed at Sango Market in Lugari district.
According to the area police chief Mrs. Eunice Kihiko the incident occured when supporters of Narc candidate and former MP Dr Enoch Kibunguchy who had been licensed to hold a rally at the market, clashed with supporters of KADDU candidate Cyrus Jirongo.
Kihiko said nobody was arrested during the incident but investigations were still ongoing with a view to arresting the suspects.
Elsewhere two men were stripped naked in a public rally as a crowd attempted to wrest away some money given to them by a politician as handouts.
The two ran into trouble at Lumama market after the former MP Dr Enoch Kibunguchy who had just addressed a campaign rally gave out some money to be dished out to his supporters.
On sensing that the two wanted to pocket the entire amount, the crowd pursued them after the candidate left and stripped them of all the money and clothes.
