A 48-year-old lotto agent called Kofi Agbavitor has been arrested for impregnating his 17-year-old handicapped daughter at Jeikrodua near Kasoa.
The victim, who is now two months pregnant, disclosed her ordeal to a neighbor who then reported the matter to the police.
Police sources say the victim said her father often slept with her at night when her other sister is not around.
Their mother left the home after the marriage with the suspect broke down.
Reports say this is not the first time the suspect has impregnated his daughter; and that he impregnated his first-born daughter and aborted the pregnancy for her.
The victim told the police her father has threatened to kill them both if they open to up to anyone.
The matter has been handed over to the Kasoa division of the Domestic Violence and Victims Support Unit (DOVVSU).
