This video appears to be from West Africa (according to their accent), although I do not know which specific country. It shows a man who was caught with a severed head and hands of a child.
The man is suspected to have beheaded and dismembered the young boy for a black magic ritual. This would be a similar case to the one we have recently seen from Ghana, whereby a farmer decapitated his own son for a ritual.
Props to Best Gore member @african-angel for the video:
