The 35-year-old Argentine victim who suffered years of psychological and physical abuse has mothered seven of her fathers children who are currently 19, 17, 16, 12, 11, 6, and 2.
Lucero, 67, is believed to have as many as 22 children in total.
Local reports have revealed that the abuse in the family had allegedly been reported at least 20 times since 1990, but the police failed to properly investigate the claims.
Prosecutors say that action was only taken when the victim herself made a complaint who mustered up the courage to report the crime because she began to fear that her father might abuse her eldest daughter.
The 'Argentine Fritzl' lived in the house with his partner, his daughter, her seven children, and his mother in law.
Although the abuse was kept under wraps, neighbours have said that they knew 'something weird' was going on in the family.
"They didn't mix much with the neighbours but people had noticed the difference in age between the man and the woman who the children called mama. No one could work out if he was the father or the grandfather," the Telegraph quoted a neighbour as saying.
The alleged victim's brother revealed that he had reported his father to the authorities nine months ago, but his mother, who worked at the Justice Department, had hushed the case up.
Lucero has been charged with systematic sexual abuse of a relative and remanded in custody. Prosecutor Marcelo Gutierrez del Barrio has confirmed that the arrest took place on May 8.
