A fourth man accused of helping to supply a gun used in the fatal Brighton siege in Victoria has been remanded to face court next week.

Joint Counter Terrorism Team police on Friday charged the Greenvale man, 36, with two counts of carrying a non-prohibited, unregistered firearm, two counts of unlicensed dealing of firearms and two counts of possessing cartridge ammunition without licence or permit.

He appeared before the Melbourne Magistrate’s Court on Friday night, but was remanded to appear on Monday.

He joins three other men who fronted the Melbourne Magistrates’s Court in the past week.

A 25-year-old Gladstone Park man was arrested on Monday and charged with dealing a firearm without a licence, possessing a firearm as a prohibited person and other offences.

A 47-year-old Westmeadows man was charged on Tuesday with being an unlicensed gun dealer and being a prohibited person in possession of a firearm.

Ascot Vale man Kane Dalrymple, 30, was also charged with being an unlicensed gun dealer.

The men allegedly supplied firearms to Brighton siege gunman Yacqub Khayre, who died in a hail of police bullets.

Khayre fatally shot 36-year-old Nick Hao, and held a female escort taken before he opened fired on police and injured three Special Operations Group officers.
