An ninth person has been charged over the execution-style murder of a NSW bikie gang leader.
Bandidos Central West chapter president Shane De Britt, 60, was shot in the head at his Eurimbla farmhouse, about 50 kilometres south of Wellington, on January 14.
Police on Tuesday arrested a 35-year-old man at Muswellbrook and later charged him with murder and taking part in criminal group activity.
Detectives had already charged eight people over their alleged roles in De Britt's murder.
Seven men - aged 22 to 58 - and a 34-year woman have already faced court and their matters are ongoing.
