Heavy “grocery items” have been flung at an ambulance in Melbourne’s CBD from a 25-storey tower while paramedics were helping a patient. The police ambulance triage team, with two police officers and a paramedic, heard three loud bangs on their vehicle in A’Beckett St at 12.25am on Sunday as they finished their work with the patient. They found a number of grocery items had been thrown to the ground, denting the ambulance and at least one other vehicle in the area, but no culprit has been identified.
