An Argentinian man allegedly locked up his wife and his son in an iron cage at home during the day for at least two years in Mar del Plata.
Local prosecutor Pellegrini said, Oviedo's 61-year-old-wife has psychiatric problems and his son (32) is autistic.
“ Old mattresses, rubble and pet food were found inside a cage with bars and an iron door. The two slept in another filthy room by night," said local prosecutor Pellegrini.
The conditions of the room were not appropriate for humans, according to Pellegrini.
The Spanish newspaper La Nacion, claimed that Mr Oviedo forced his son to eat animal food, because police found animal food and fuel in the cage with him.
Mr Ovideo was arrested on Friday and charged with captivity, he has denied all charges.
There are lots of stories similar to this case. In April 2008, in what is known as the Fritzl Case, Elisabeth Fritzl, who was born 6 April 1966, was held captive for 24 years in a concealed corridor in Australia by her father. Frtizl Case came to light in April 2008 when she was 42-years-old. During her enslavement she was physically attacked and raped several times.
The other story is from Bosnia. A German Woman, 19 years old, was held captive for eight years. Milenko and Slavojka Marinkovic were arrested in the village of Karavlasi in May 2012. Girl was forced to eat swine feed.
In another slavery case in London, a married couple, Mr Balakrishnan, 73, and his 67-year-old wife had held three women hostage for more than 30 years. One of them was born in that house during this time.
