Cord has accused Jubilee of instigating violence against its supporters in Central Province.
Ochieng Mbeo, a former MP and a member of the Cord communication team, said the party was disturbed that their rallies in Mt Kenya were disrupted in Embu by youths chanting pro-Jubilee slogans.
Mbeo said Jubilee presidential candidate Uhuru Kenyatta had signed a code of conduct and should restrain his supporters from disrupting Cord campaigns.
"In Meru, two Jubilee branded helicopters deliberately landed at the venue of a Cord rally disrupting the meeting," he said.
Mbeo said on Monday Medical Services Minister Anyang Nyongo's brief case was stolen with an undisclosed amount of money in Limuru.
And on Wednesday a Cord campaign team led by businessman Peter Kuguru was attacked and their convoy of vehicles stoned in Kiambu.
He said rowdy youths broke into his vehicle harassed his people and stole the briefcase which contained his documents.
"They also took off with campaign materials that were meant for the rally," Mbeo said.
He added: "Clearly, this shows how intolerant some people are. It is barbaric, archaic and unacceptable especially when everyone is talking about peaceful campaigns and elections."
Mbeo said Prime Minister Raila would be touring Kiambu County from Tuesday to drum up support for his bid and they expect a peaceful campaign as he goes round the populous county.
On Thursday, Cord was accused by both Jubilee and Amani coalitions of using propaganda and violent language against their presidential candidates.
In separate statements, Jubilee and Amani accused Cord of employing dirty tricks as campaigns enter the final lap.
In a letter to the Independent Electoral Boundaries Commission, TNA secretary for Legal Affairs Jasper Mbiuki accused Cord leaders of brandishing weapons and using demeaning language against Uhuru in their campaign rallies.
Amani accused Cord of employing propaganda to campaign against their presidential candidate Musalia Mudavadi especially in Western Province.
