Kiambu Governor William Kabogo has been summoned by a house committee after a petition to parliament by Kikuyu MP Kimani Ichung'wa.
Ichung'wa alleges that Kabogo is funding and using private militia and police to harass MPs in Kiambu county.
The MP is among politicians from the county at loggerheads with the governor.
“The militia is not just backed by the governor. It is managed and funded by the county government and the governor himself,” Ichung'wa claimed.
Members of the Administration and National Security Committee said the governor and the heads of the security agencies should appear before it to respond to the allegations made by Kiambu residents.
Ichung’wa described the various incidents where he said the armed militias, backed by the police and some employees of the Kiambu County government, have clashed with the MPs and their supporters.
“My worry is that in the run up to elections, if you allow impunity to reign, the 2007 and 2008 violence will look like a children’s dance,” said Ichung'wa.
