A father dubbed "Argentina's Josef Fritzl" reportedly had five children with the daughter he locked away and repeatedly raped in his home, Argentine police have revealed.
The man is accused of repeatedly raping his daughter since childhood in a case that appears to chillingly echoes that of Austrian monster Fritzl.

The 53-year-old is accused of raping the woman and violently threatening their illegitimate children if they reported him.
The man is said to have claimed his daughter was his reclusive wife when questioned about their relationship.
He was only arrested when the husband of another daughter contacted the police.
Manuel Ontiveros, from the city's police sex crime unit, said: "The complainant stated the girl had no boyfriend and it was the father who had abused her and got her pregnant.
"The man sometimes passed his daughter off as his wife, when he was asked by neighbours or people outside of the family."
It has been reported that the man had previously dodged jailed despite being arrested for abusing one of his other daughters, who then ran away.
But because it was not a rape charge, the unnamed father was merely given a suspended sentence.
Authorities are also looking into whether the daughter's mother, who left the family home six years, was aware of her husband's horrific sexual abuse.
Local media has said the case has chilling echoes of Austrian monster Josef Fritzl, who fathered seven children with daughter Elisabeth, who he kept locked inside a basement for 24 year.
