Aldinga Beach stabbing: Champion cyclist revealed as victim of brutal attack as police investigate links to bikie gangs

Commonwealth Games cycling champion Jay Sweet has been revealed as the victim of a brutal stabbing attack at Aldinga Beach.

Sweet, 48, was rushed to hospital after receiving a stab wound to his hand after an alleged assault at his residence on Hamilton Road  in Adelaide during a family barbecue. 

Nine News footage showed Sweet being loaded into an ambulance, with the knife still protruding from his hand.

The 48-year-old is a former professional cyclist who competed in the Tour de France and won gold during the 1998 Commonwealth Games in Kuala Lumpur. 

At around 12.40pm on Monday, emergency services responded to reports of the alleged incident, with detectives surrounding the Hamilton Road property before police broke down the door using a mallet and a crowbar.

Those inside the property assisted police with their inquiries as cops tried to determine who stabbed Sweet and their motive.

According to News Corp, police are investigating if the incident is connected to two reports of firebombings this week at Aldinga Beach and Old Reynella. 

They are also investigating if there are bikie links to the stabbing and arsons, with News Corp claiming there are probes into whether the incidents are part of a turf war relating to the control of the drug market in the southern suburbs of Adelaide.

Neither Sweet or his family are accused of any wrongdoing. Police do not allege that they are involved in bikie gang or drug activity.

The cyclist retired in 2003 and moved to New Zealand, before returning to Adelaide in 2012. 

He was once considered the fastest sprint cyclist in Australia, during his peak years.

Nowadays, Sweet runs a stone mason business called 'Sweet Stone'. The company's Facebook page says it offers 'construction of all types of stone work. Dry stack and wet walls. Real stone and artificial veneers'.
