The man has been jailed for sexually abusing his daughter, whom he located through the reality TV show after 38 years.
The daughter's ordeal began in 2003 when she was watching an edition of El Diario de Patricia (Patricia's Diary), a reality show that specialises in family scandals, marriage breakdowns or long-lost relatives appearing by surprise live on air.
The 38-year-old spotted her father, who told viewers that he had not seen his two daughters since 1966 when he split up with their mother, reports Times Online.
She then decided to get in touch with him after they spoke on the telephone. They met for the first time in Torremolinos, near Malaga.
The mood changed when the father kissed her on the lips during one of their seafront meetings.
Instead of refusing to see him again, she returned with him to her home in Malaga, where he sexually abused her.
The court was told that the abuse continued during several other meetings and he later raped his daughter.
A psychiatric report, submitted to the court, said that the woman did not react in the normal way when her father started to abuse her "because of the lack of support which she had suffered throughout her life".
In court, the father claimed that his daughter had invented the whole story to get revenge because he abandoned her as a child.
El Diario de Patricia has already come under scrutiny in past years, especially after a young Russian woman was killed by her former partner, just days after the two has appeared on the programme and she had refuse to marry him.
After the killing, it emerged that the couple had a violent past and the woman had been granted a restraining order against her ex.
