The man from Gladstone Park, north of Melbourne, was charged by police with a range of offences after it was alleged he supplied a firearm used in the attack which left 36-year-old Kai Hao dead.

Charges also include possessing cartridge ammunition without a licence or permit, committing an indictable offence while on bail and being the unlicensed dealer of a Category A firearm.
More than 150 police officers were involved in last week's counter terror operation which saw warrants executed at Ascot Vale, Glenroy and Gladstone Park.
The 25-year-old will appear at the Melbourne Magistrate's Court on 14 June.
A 32-year-old Glenroy man who was arrested during Friday's raids and interviewed by police for aiding and abetting the commission and engagement of a terrorist act, was later released without charge, the ABC reported.
