Tributes have poured in for two Irish teenagers who died within hours of each other while on holiday in Greece to celebrate the end of their exams.
Andrew O'Donnell and Max Wall, both 18, had graduated from St Michael's College secondary school this year and travelled to the island of Ios as part of a large group.
During a night out on Saturday, Andrew became separated from a friend while walking back to their accommodation and was reported missing.
