An Adelaide man has faced court charged with murder and attempted murder over the 1994 bombing of the National Crime Authority building.
Domenic Perre, 61, appeared in Adelaide Magistrates Court on Thursday in relation to the bombing, which killed Detective Sergeant Geoffrey Bowen and injured lawyer Peter Wallis.
Perre made no application for bail and was remanded to reappear in court in July.
His lawyer, however, did not rule out making an application in the future in a courtroom more than half full of police officers and detectives.
Det Sgt Bowen was killed and Mr Wallis injured when a parcel bomb was delivered to the NCA building in Adelaide's CBD.
Perre's arrest follows a joint investigation by a number of state and federal authorities including Australian Criminal Intelligence Commission, along with the Director of Public Prosecutions, who conducted a review of the evidence.
It has been one of the state's highest-profile cases, with a reward of $1 million issued in 2008 for information leading to the conviction of the person or people responsible.
In 2016, police revealed that the renewed investigation into the bombing had advanced.

They found the make-up of the bomb and technological improvements meant it was possible to locate DNA on remnants of the device, which could be later checked against the profiles of possible suspects.
Sixty-five items were sent to the world-leading Netherlands Forensic Institute for further examination, while partial DNA profiles and fingerprints were recovered from other crucial exhibits.
Det Sgt Bowen was originally from WA and the state's police union said it was pleased someone had been charged after such a long time.
"At the time, the death of Geoffrey Bowen rocked the WA police family and 24 years later, it is a major achievement to have someone charged," president George Tilbury said.
