Peter Karanja, who is charged with murder of Dutch tycoon Tob Cohen alongside Sarah Wairimu Kamotho has been arrested.
Karanja was arrested at the Milimani Law Courts in Nairobi on Tuesday afternoon.
A warrant of arrest was issued by a Naivasha court, where he is wanted for robbery with violence.
The arrest comes shortly after the High Court consolidated the two files of Ms Wairimu and Mr Karanja’s and the two pleaded to the charge of killing Cohen, afresh.
