In the 1960s, from the age of two, Patrick Walsh and his brothers were locked away at the notorious Artane industrial school in north Dublin.
While there he suffered severe physical abuse at the hands of Christian Brothers, the Catholic order charged with running the schools across Ireland.
He suffered more torment after one of his brothers escaped from Artane, and was regularly subjected to savage beatings and other physical punishments.
He is now a businessman living in Camden, north London
