Friends found Mr Sofer-Schreiber lying dead with multiple stab wounds in his Hall Street unit on Saturday, December 28, two days after he was last seen alive.

There was no sign of forced entry or a struggle at the scene, and police did not believe the death to be motivated by burglary or robbery.

They have earlier spoken with a number of former housemates of Mr Sofer-Schreiber as part of their investigations, and were stating they had identified ‘‘persons of interest’’ since at least January 4.

The avid punk fan’s death triggered an outpouring of emotion from friends and loved ones.

Police launched a major homicide investigation following the death, which culminated with the arrest of a suspect on Friday.

The accused killer will appear in morning bail court on Saturday.

Criminal Investigations Detective Superintendent Paul Shakeshaft said the arrest had been the result of a major effort by police.

“We’ve had a dedicated team working this investigation, with support from multiple areas of ACT Policing, the wider AFP and members of the public. For the detectives working this case, it has been intensive and exhaustive at times, I thank you for your commitment and dedication,” he said in a statement.

“For the friends and family of Mr Sofer-Schreiber, we are sorry for your loss, which we know you deal with every day however hope this arrest gives you some peace of mind.”

Mr Sofer-Schreiber was legally blind and was believed to have lived alone at the time of the death. He was not thought to have been seen since Boxing Day, two days before he was found dead.

Police searched a NSW property near Grafton last month as part of their investigations.

A warrant as executed and a thorough search of the area was conducted, including a number of campsites and dams.

They seized several items which were submitted for forensic testing.

Mr Sofer-Schreiber, affectionately known as the "ginger ninja", was a fixture in the local punk scene.

Friends remembered him as ‘‘unique, loveable, kind-hearted’’ and as ‘‘everyone’s designated little brother’’.

They have since started fundraising for a music festival in his honour, named the Annual Ginger Ninja Punk Festival.
