Casa Pia is a Portuguese state-run institution that has provided education and residential care to poor and orphaned children, running ten orphanages and schools caring for roughly 4,600 children. In the early 2000s, an investigation found that an employee of the institution had run a child prostitution network involving around 100 boys, and the resulting criminal case became one of the longest-running trials in Portuguese history. It was the first institutional child sexual abuse case in the country to reach trial.
Concerns about abuse at Casa Pia predate the scandal's public breakout. From 1975, Casa Pia teacher Américo Henriques reported allegations of sexual abuse to the institution's leadership and to police. In 1981, the Portuguese Judiciary Police accused a caretaker at a Casa Pia children's home of raping dozens of children over roughly three decades, with some abuse reportedly predating Portugal's 1974 Carnation Revolution; those early allegations did not lead to prosecution.
The scandal resurfaced publicly in September 2002, when the mother of a child referred to in press accounts as "Joel" complained that staff at a Casa Pia house had abused her son. That year, journalist Felícia Cabrita published the first press report on the allegations, in the weekly magazine Expresso, after a former Casa Pia pupil alerted her to the case; her reporting drew on a recorded conversation and on documentation from Henriques. Former Casa Pia residents subsequently came forward publicly with further accusations against institution employees and associates.
A criminal trial opened in 2004 and ran for more than five years, with testimony from 32 alleged victims among more than 800 witnesses and experts. On 3 September 2010, six men were convicted of paedophilia and related crimes committed in the late 1990s and early 2000s: television presenter Carlos Cruz (sentenced to seven years); Casa Pia employee and former pupil Carlos Silvino, known as Bibi (eighteen years); lawyer Hugo Marçal (six years and two months); former Casa Pia governor Manuel Abrantes (five years and nine months); physician Ferreira Diniz (seven years); and former diplomat and ex-UNESCO ambassador Jorge Ritto (six years and eight months). Ritto had previously been removed as Portugal's consul in Stuttgart, in 1969–1971, after German authorities raised concerns about his conduct with an under-age boy. The full written ruling, roughly 2,000 pages long, was delayed from an original 8 September release date because of a technical glitch and was published on 13 September 2010; chief prosecutor Miguel Matias said the victims were satisfied with the outcome.
Not everyone investigated in connection with the case was convicted. Paulo Pedroso, who had overseen Casa Pia as Secretary of State for Labor and Training from 1999 to 2001, was detained on paedophilia-related charges that were later dropped; in September 2008 a Portuguese court ruled he had been wrongly detained and ordered the state to pay him 100,000 euros in compensation. Casa Pia's post-scandal director, Catalina Pestana, told parliament and media as late as 2007 that abusers might still be present within the institution. In October 2020, the Judicial Police arrested a separate individual, 74-year-old Cascais businessman António Olmos, on child sexual abuse allegations reportedly spanning about two decades; he was remanded in custody pending further proceedings. Olmos was reported to have socialized with two of the men convicted in the original case.
