When the Sydney radio host Ray Hadley opened his house to more than 60 students on Friday night, it was always likely to be a boisterous affair. The teenagers – all friends of Hadley’s daughter – were in celebration mode having just attended their year 12 formal at Hills Grammar School. Within hours the graduation party had turned ugly: Hadley’s electric front gates were allegedly kicked off their hinges and there were several heated exchanges with a drunk student believed to be responsible, reports the SMH.
