A 62-year-old Argentinian man has been arrested on suspicion of abusing his daughter for 30 years and fathering 10 children with her, a news report said.
The 43-year-old woman only dared to report the crimes to police in Santa Fe province when her father was arrested for cattle theft, the Notife online newspaper reported Wednesday.
Genetic tests confirmed the victim's statements. She also said her father kept threatening her with a gun.
The children, of whom eight are still alive, did not know that their grandfather was also their father.
Only her oldest son found out and afterwards killed himself, the victim said. When she got pregnant, she had to tell the older children and the neighbours that she had slept with other men, who had then run off, the woman said.
Investigating judge Virgilio Palud said that sexual abuse within families was very common in the northern part of the province. If found guilty, the culprit faces 20 years in prison.
Last month, a man was arrested in Cordoba province on charges of having raped his daughter for 20 years. She bore six of his children.
