A 34-year-old man has been charged with the murder of Rebels bikie boss Nick Martin who was assassinated at a Perth Motorplex in December last year.
The man has been charged with one count of murder and two counts of unlawful act or omission with intent to harm.
He is due to appear in a court on Wednesday.
Martin was assassinated by a suspected sniper in front of horrified children during an event at Kwinana Motorplex on December 12, 2020.
Police believe that Martin was shot from about 300m away while attending the event with his wife Amanda.
