Gilgil MP Martha Wangari has moved to court in a fresh suit against her ex-husband Peter Njoroge who is one of the suspects in the murder of Dutch tycoon Tob Cohen.
MP Wangari is seeking to have the courts bar her estranged husband from seeing their children until the matter is decided.
Citing that the children are minors, Ms Wangari argues that they ought to be protected from "mental anguish, possible ridicule, stress, stigma and accompanying danger" that would possibly result from interacting with their accused father.
"It is important that his true character be exposed before the honourable court can grant him any orders of access and interaction with the children
"That it will not for the best interest of justice [and] fairness for the minor to interact with the respondent, a person suspected of acts of violence, murder and immorality until the criminal process against the accused is finalized and verdict made," court papers read in part.
Cohen murder trial
Wangari's applications comes just days after Mr Karanja also made an application before the courts seeking to be granted access to his children as he is in remand.
His application is yet to be determined.
Karanja is co-accused with Sarah Wairimu, Cohen's wife, who is also in holding after she pleaded not guilty to the charges against her.
Sarah's bail application will be determined on Friday.
