Arrested: Sam Ibrahim.
On face value, it appeared to be a series of innocent text messages between a well-known former bikie boss and an ageing rocker discussing plans for a workout.
''We trainin 2 mora mate,'' Rose Tattoo drummer Paul DeMarco allegedly wrote in a text message to his trusted friend, former Nomads boss Sam Ibrahim, in February.
According to messages intercepted by police and contained in police documents, the next day Mr DeMarco followed it up with: ''Hi mate, r we training 2 day.''
But police will allege in court the ''training'' was the code name used by the pair for the guns they were selling for as much as $30,000 a piece as part of an illegal firearms syndicate operating in Sydney's western suburbs.
Mr Ibrahim, the 45-year-old older brother of Kings Cross identity John Ibrahim, and Mr DeMarco, whose band is known for hits such as Rock 'n' Roll Outlaw, were arrested in a series of raids in Sydney and Wollongong last Tuesday. Mr Ibrahim's younger sister, Maha Sayour, who last year changed her name to Jazz Dior, was also arrested.
All three are alleged to have been key players in an illegal firearms syndicate that sold 13 guns, including pistols and shotguns, to an undercover officer since last October.
It is understood police will allege that Sayour, who runs a Wollongong car wash business, and another man helped source the guns for Mr Ibrahim. Mr DeMarco was allegedly the frontman who sold the weapons.
Among the firearms Mr DeMarco is alleged to have sold are two fully operational Uzi-style machineguns, both fitted with silencers and sold with ammunition, for $30,000 each.
The drummer allegedly told the undercover officer that Mr Ibrahim was the one who set the price, and that those two guns could have been sold for up to $40,000 each.
It will also be alleged that the syndicate offered to provide 10 brand-new 9mm Beretta pistols for $9000 each but their delivery was thwarted by high-level security.
Police will allege that, in a bid to hide their conversations about their gun trade, Mr Ibrahim and Mr DeMarco spoke in code, using the term ''training'' when inquiring about the latest gun supply.
Police say they have no evidence that Mr DeMarco took part in any form of physical exercise.
Police will also allege that Mr Ibrahim and his sister usually spoke in English but changed to Arabic when they were talking about organising and supplying the guns.
Mr DeMarco, 55, who police will allege was the kingpin of the enterprise, has been charged with 27 firearms offences.
Mr Ibrahim has been charged with five offences involving the sale of firearms and possession of steroids allegedly found when police raided his Greystanes home.
Mr Ibrahim's solicitor, Brett Galloway, said the case against the former bikie boss was ''soft''.
''It will have no spine, like any of the serious prosecution attempts against Sam in the last 20 years,'' Mr Galloway said.
''There's no substance and I think time will show that.''
All three were refused bail when they appeared in court last week. The matter will return to court this week.
Police also arrested two other men, including Blacktown man Colin Wood, 43, after allegedly finding a crossbow, ammunition and revolvers in his home.
Assistant Commissioner Denis Clifford said the operation led by Penrith detectives had made a ''significant dent'' in the sale of illegal firearms in Sydney.
