The suspect, whose description fits Arthur Simpson-Kent, was arrested at Busua, some 200 km west of capital Accra.
The sources said police had been on the tail of the suspect who was reported to have fled through Glasgow, Scotland to Ghana over the past two days.
Simpson-Kent had been declared wanted when police found bodies of Sian, Zachary and Amon on Tuesday, buried in shallow graves in their own backyard garden, in Britain.
He was believed to have travelled to Ghana the same day after police visited him at their home.
Post-mortem reports according to British media said the deceased had died from “head and neck injuries”, before being hidden in their own garden.
He promised that details would be provided by Director General of the Criminal Investigations Department (CID) as soon as everything was confirmed. Enditem
