The alleged national president of the Hells Angels bikies gang has been denied bail over firearms charges a magistrate described as "incredibly serious".
Police seized a loaded handgun and steroids during a raid at Luke Moloney's Reservoir home on Wednesday morning after he was served with a Firearm Prohibition Order.
The 41-year-old has been charged with several offences including failing to surrender a firearm and possessing an unregistered handgun.
Moloney on Wednesday night faced the Melbourne Magistrates Court where his barrister Damian Sheales conceded there was a "strong case" against his client but applied for bail with a $10,000 surety.
"The police obviously know who this man is - he's on their radar," Mr Sheales told the court.
"And he understands if he gets arrested again ... it will be a very different ball game."
However, magistrate Rose Falla rejected Moloney's bail application on the grounds he posed an unacceptable risk.
"I consider the possession of any firearms to be incredibly serious - especially a loaded one and especially when you're a prohibited person," Ms Falla said.
"Firearm crime has exponentially grown in the last five years."
Moloney will next face the Heidelberg Magistrates Court on August 19.
Two other patched members of the Hells Angels, a 22-year-old Mickleham man and a 56-year-old Essendon man, were also served with Firearm Prohibition Orders.
Once issued, an FPO remains in effect for 10 years for adults, and the individual is prohibited from having any firearm or firearm-related item such as ammunition.
They are also unable to enter a range of premises including firearms dealers, shooting ranges or firearms clubs.
In separate raids on the Rebels outlaw motorcycle gang, 11 people were arrested and charged with 17 FPOs issued.
The Illicit Firearms Squad along with detectives from the Echo Taskforce, Western Region Crime Squad, Mildura Crime Investigation Unit, Dog Squad and the Australian Federal Police's National Anti-Gangs Squad were involved in the two-day operation, which started on Tuesday.
Among those charged is a 36-year-old Irymple man, who is also the gang's sergeant at arms, with allegations of possessing cannabis and possessing proceeds of crime.
During those raids, police say they seized items including two firearms, three imitation firearms, firearm parts and ammunition, prohibited weapons including swords, nunchucks and a conducted energy device, cash, drugs, illegal fireworks and an explosive device.
