Last January, former teacher Matt George and care worker John Muldoon were jailed for a total of 28 years for physically and sexually abusing children at Kerelaw between the 1970s and 2000s.
It was the second time the pair had been convicted of abuse at the school.
Earlier this month, Police Scotland confirmed 10 new arrests had been made in connection with abuse allegations at the school.
The force confirmed seven men and three women – aged between 52 and 77 – were questioned about the treatment of youngsters there.
The Crown Office and Procurator Fiscal Service later confirmed it had received reports relating 10 individuals.
A 2009 report by Glasgow City Council – which had taken over the school from the old Strathclyde Regional Council – found Kerelaw had been badly managed.
Evidence about the school was also heard by the Scottish Child Abuse Inquiry in March but it has yet publish its findings.
