Senior Sergeant Blain said the incident was reported to police days later, on March 1, and investigations lead to the 19-year-old s arrest on March 2. Sen-Sergeant Blain said it would be alleged the incident was a one-punch assault resulting in serious injuries, and followed the launch of the Assault Free Zone campaign targeting anti-social and alcohol-fuelled violence in the district. The incident was recorded on City Safe cameras, which helped in the investigation. He said Whitsunday police would continue cracking down on violent behaviour in the Airlie Beach district. The 19-year-old man is scheduled to appear in Proserpine Magistrates Court on April 12.
