Police Scotland have confirmed they carried out an investigation into historic sexual abuse at Glasgow’s prestigious St Aloysius’ College.

A former pupil, now in his 60s, claims he was sexually abused over two and a half years by two Jesuit priests, and physically abused by another Jesuit and also by a lay teacher.

All but one of the four men alleged to have been responsible for the abuse have since died, although officers interviewed the survivor, who now lives in England. They also spoke to one of the other men before he died.

Police Scotland said they had investigated the claims but due to a lack of corroboration, a report was not made to the procurator fiscal.

Now a lawyer acting on behalf of the man is appealing for other former pupils to come forward if they witnessed or experienced abuse.

The alleged victim, identified only as Andrew, who is 64, said the abuse had largely consisted of being required to perform sex acts on one of the priests. The physical abuse had been provoked when he had informed another priest what was happening, and was beaten himself in response, he says.

He told the Sunday Mail: “I went to one of the priests and said that another had touched me under my shorts but unfortunately he stuck me in to the others. I was summoned and given nine lashes on the bare back, bottom and legs.”

Patrick McGuire, a partner with ­Thompsons solicitors which is ­representing Andrew, said his story was powerful and compelling, adding: “We will do everything in our power to obtain justice for him.”

However Mr McGuire said his case would be greatly strengthened if any other survivors of abuse at St Aloysius’ College were to corroborate his claims. “We are today encouraging any other ­survivors of abuse St Aloysius’ who have not yet come forward to now do so,” he said.

St Aloysius’ ­College told the Sunday Mail: “The college has clear and robust safeguarding ­procedures in place to protect the safety and wellbeing of our pupils.”

A spokeswoman for Police Scotland said: “We can confirm officers received a report in 2017 of historical sexual abuse on a 64-year-old man, which occurred in the 1960s at St Aloysius’ School. Inquiries were carried out, however, there was insufficient evidence to report to the Crown Office and Procurator ­Fiscal Service.”
