A teenager is in critical condition, while a 20-year-old suffers serious injuries after a violent clash erupted at a shopping center in northern Adelaide.

The altercation at Elizabeth City Centre led to a lockdown this afternoon, resulting in one individual’s arrest.

Emergency services rushed to the scene shortly after 2 p.m. yesterday, responding to reports of a confrontation involving four males inside the shopping complex.

Police acted quickly, apprehending a suspect on-site.

Meanwhile, first responders administered medical aid to two individuals who had sustained stab wounds during the fracas.

A 16-year-old boy was stabbed in the leg, and a 20-year-old man suffered a stab wound to the abdomen.

The pair were rushed to hospital, with the 16-year-old’s condition described as life-threatening.

A 16-year-old boy was arrested and charged with two counts of causing serious harm.

He was refused bail and will appear in the youth court on Monday.

Police are working to identify and locate the other male involved in the altercation.

“I want to reassure the Elizabeth community that this was not a random incident,” Superintendent Amit Sareen said.

“Police responded quickly and apprehended the suspect at the scene, and have seized the weapon that was used.”

Investigations are continuing.
