Two men have been charged after a paramedic was assaulted and others threatened in a “cowardly” attack while treating a woman with cardiac arrest at a bar in Sydney’s Darling Harbour. Paramedics were called to King Street Wharf soon after midnight, where they found the 22-year-old woman unconscious and with a group of “agitated and aggressive” people, police said. The public order and riot squad was called after one paramedic allegedly was pushed. Another man operating a camera was arrested for hindering police.
