A fly-in, fly-out worker suffered serious head injuries after he was allegedly punched, causing him to fall and hit his head on the ground, after a dispute over music at a Pilbara mine site. The 52-year-old victim, from Baldivis, had to be flown to Royal Perth Hospital. Police allege the victim and a man in his 40s became involved in a physical dispute at Rio Tinto’s Gudia-Darri mine site near Newman about 8.45pm on July 10. “During the altercation the man in his 50s was punched, causing him to fall backwards and hit his head on the concrete ground,” a police spokeswoman said. “The man received serious head injuries and was airlifted by the Royal Flying Doctor Service to Royal Perth Hospital for treatment.” It’s understood the victim had been playing music before the site’s curfew and the accused had told him to turn it off. The incident happened a day before the site introduced a four-drink limit in response to a series of alleged sex assaults in the mining industry. Investigations from Rio Tinto and WA Police are ongoing.
