Man used his sister for money ritual

A man in Tanzania has been arrested for allegedly putting his sister in a septic tank for four years for money rituals.

The unidentified man who is believed to have lied to people that his sister was dead instantly became rich after her supposed death.
His maid is the one who discovered the girl in the tank after being curious about her boss's visits to the tank every morning before going for work.
The pictures below show the girl before she was put in the tank and after being rescued from the tank.
