A 22-year-old man has been charged with murder following the execution-style shooting of Bandidos outlaw motorcycle gang Central West Chapter president Shane De Britt.
Officers from Orana Mid-Western Police District arrested the man outside of the Menace Ink Tattoo shop in Wellington on Wednesday at around 9am.
Search warrants have been issued for both the Menace Ink Tattoo Shop and the 22-year-old's residence.
This is the third arrest, alongside a 58-year-old male and a 39-year-old male last week, concerning the January murder. Police said the three men were allegedly among a "criminal group" or "rival criminal network".
Detective Chief Inspector Wayne Walpole said along with the murder charge, the man has also been charged with aggravated firearms and participating in a criminal group.
"We believe there are other people involved in this murder, charges will be determined going forward," Mr Walpole said.
"Investigations are ongoing, we're dealing with a lot of information from both the public and from doing basic police street work. I am confident there will be more arrests."
Mr Walpole said others involved in the murder "should be feeling pretty uncomfortable right now".
"If they would like to turn themselves to the police, we will certainly accommodate them," he said.
Mr Walpole said he believes any plans of retaliation were prevented by the presence of the Strike Force Raptor.
"Evidence of this is the fact that there hasn't been any," he said.
The 22-year-old remains in custody at Dubbo Police Station. Investigations by the State Crime Command's Homicide Squad, assisted by Criminal Groups Squad and Dubbo detectives, are ongoing.
