There's been yet another arrest following the execution-style murder of bikie gang defector Shane Bowden, with a 10th alleged member of the Mongols charged over the Gold Coast slaying.
A 26-year-old man from Ipswich was charged on Wednesday with the murder of Bowden, who was shot 21 times by two gunmen in the driveway of his Gold Coast home last October.
Nine other alleged Mongols members have been charged with his murder. Police say the gang knew exactly when to stage the ambush after they secretly fitted a tracking device to Bowden's black BMW.
The ninth arrest in the case happened on Tuesday, when police charged Adam John Murphy, 37, of Wanora, outside Ipswich.
The arrests began on Saturday, when police moved on the alleged mastermind of Bowden's execution.
They descended on the Ipswich home of Ian Robert Crowden, 46, the man police say is the president of the Brisbane West Chapter of the Mongols.
He stands accused of directing and financing the murder.
On Sunday, police raided properties across southeast Queensland, and charged seven other alleged Mongols, aged 23 to 41, with murder.
On Wednesday, Detective Superintendent Brendan Smith said officers would continue to dismantle "the so-called brotherhood and code of silence surrounding the death of Shane".
"This was a calculated and premeditated act with many people involved in varying aspects of the execution," he said.
"There is no loyalty when you are facing a significant time behind bars away from your family and friends. This is the time to speak up and take advantage of the indemnity on offer and the $250,000 reward."
He said every single person involved would be brought before the courts, no matter how long it took to achieve.
Gold Coast criminal lawyer Michael Gatenby has said he'll be "very surprised" if a murder charge sticks for the bulk of the defendants given the prima facie case.
Bowden was initially a member of the Finks criminal bikie gang, and part of its "terror team" jailed over the Gold Coast's so-called ballroom blitz brawl in which three people were shot and two stabbed in 2006.
After his release, it's understood he defected to the Mongols but was booted out and rejoined the Finks just before he was shot.
All 10 murder-accused remain in custody and are due to have their cases mentioned again on August 2.
The others who've been charged are Junior Jasmine Torope, 29, Joshua James Small, 29, James Winston Mau'u 23, Haydn Thomas Forbes, 25, David Steven Meatuai, 41, Fidel Gunes, 29 and Peter Michael Cummins 35.
