Judy Wangui, one of the suspects in the murder of Mary Wambui, raised complains that detectives have been torturing her.
Ms Wangui, through her lawyer Cliff Ombeta, told Kiambu Senior Principal Magistrate Stella Atambo that two female officers from Juja Police Station assaulted her on Friday night.
Besides the injuries Wangui claims that the officers who were in charge of her went as fas as inserting pepper in her private parts.
She confirmed that she had reported the case to the OCS but it was not addressed.
She revealed this during the hearing of an application by detectives from the homicide unit who had requested to hold her, her boyfriend Joseph Kori and car hire dealer Michael Githae Mathenge and detain them for another 14 days.
The new detectives who took over the investigation two days ago told the magistrate that they want to tie up loose ends before charging the suspects.
They described the murder investigation as complex and technical and said there are pending issues that need deeper probing.
Mr Korir who in many occassion got emotional asked the court to release him to take care of his children and go bury his wife.
The court allowed for their detention for nine more working days at Muthaiga Police Station.
