Police have charged a 25-year-old man over the fatal drive-by shooting outside Melbourne's Love Machine nightclub earlier this year.
Two people were killed and four others injured in the attack on the nightclub in Prahran, in Melbourne's inner south-east, in the early hours of April 14.
Richard Arow, 28, and Aaron Khalid Osmani, 37, died in the days after bullets were sprayed from a moving car at the crowd outside.
Police arrested Moussa Hamka in the northern suburb of Epping on Saturday and seized a handgun.
He has been charged with being an accessory after the fact to murder, possessing a firearm, stalking, making threats to kill and other offences.
Mr Hamka appeared before the Melbourne Magistrates' Court on Sunday morning.
He made no application for bail and will appear for a filing hearing on Tuesday.
It is the first arrest in the ongoing investigation, which has involved Victoria Police's anti-bikie Echo Taskforce and homicide squad.
Mr Arow's family gave an emotional plea for people with information to come forward earlier this month, as police released CCTV vision of a maroon ute they believed was involved.
On Tuesday, they released images of another car they believed was accidentally torched following the shooting.
Detectives are continuing to appeal for anyone with information to come forward.
Anyone with information is asked to contact Crime Stoppers.
