Two men and a woman are in police custody and are expected to be charged in connection with the shooting murder of Jason De Ieso at his Pooraka business in 2012.
As part of Operation Persist, the men were arrested this morning (Friday 2 August) and are currently being interviewed by detectives from the SA Police Major Crime Investigation Branch. They are expected to be charged with murder.
The woman was arrested by detectives in Queensland and police will apply for an extradition this afternoon. She is expected to be charged with assisting offenders.
Mr De Ieso, 33, was shot dead in his workshop in Langford Street, Pooraka on 21 November, 2012.
CCTV footage from the premises, previously released by investigators, shows nine men walking towards the front of the business, with at least six of those carrying firearms.
The men opened fire, killing Mr De Ieso, before running from the scene.
The murder was believed to be linked to a dispute between the outlaw motorcycle gangs the Finks and the Hells Angels, however police stress that Mr De Ieso was an innocent bystander, caught up in the tensions.
Further details are expected to be released later today.
