Police are investigating a major disturbance in Newcastle's suburb of Mayfield after a promotional event organised by streetwear brand Bad Apples attracted hundreds of people and escalated into widespread disorder involving dirt bike riders, crowd clashes, and property damage.

The gathering was held at Dangar Park following a social media promotion offering merchandise giveaways. Authorities estimate that between 150 and 200 people attended, while dozens of riders on unregistered dirt bikes and trail bikes were seen performing stunts throughout the park and surrounding streets.

Residents described scenes of reckless riding, burnouts, damaged grassed areas, and dangerous behaviour around pedestrians. Videos circulating online allegedly show riders performing stunts near crowds, while police reported concerns for public safety as the event grew increasingly difficult to control.

New South Wales Police deployed significant resources to the area, including ground units and aerial support. Several nearby roads were temporarily closed to manage safety risks, and officers were required to intervene when tensions escalated within the crowd. Capsicum spray was used during attempts to restore order.

Authorities confirmed that one woman was arrested following an alleged assault during the event and was later released pending further inquiries. Police also reported that a patrol vehicle and at least one civilian vehicle sustained damage during the disturbance.

Newcastle City Commander Superintendent Kylie Endemi condemned the behaviour of those involved, stating that investigators are reviewing body-worn camera footage, aerial recordings, and public videos to identify offenders. She warned that further action could follow as police continue their inquiries.

Newcastle Deputy Lord Mayor Charlotte McCabe said the city council had not approved or been notified of the event beforehand. She indicated the council would seek compensation for damage caused to public parkland and criticised attempts to profit from footage of dangerous behaviour.

The clothing company at the centre of the promotion has previously held similar giveaway events in other Australian locations. At the time of reporting, police investigations remained ongoing as authorities worked to identify those responsible for reckless riding, property damage, and other alleged offences.
