Gang Crime Squad detectives have charged three members of the Rebels Outlaw Motorcycle Gang following a serious assault.
According to police the bikie trio, including a 32-year-old from Secret Harbour, were allegedly involved in a physical dispute that left a 27-year-old with serious injuries.
About 11:55pm on June 10 officers from the Rockingham Police Station were flagged down at a service station on Warnbro Sound Avenue in Warnbro, and taken to a seriously injured man sitting in a car.
The vehicle the man was sitting in also had serious damage including smashed windows.
An ambulance was called and the man was taken to Rockingham Hospital, before being transferred to Royal Perth Hospital.
It is believed the assault was in relation to a dispute over the ownership of a vehicle.
As part of the investigation detectives from the Gang Crime Squad executed search warrants in Hammond Park, Waikiki and Rockingham Thursday morning including the gang's main clubhouse of the Rockingham chapter of the Rebels OMCG.
Three men were arrested and have since been charged.
The President of the Rockingham chapter of the Rebels OMCG, a 38-year-old man from Waikiki, has been charged with grievous bodily harm and criminal damage.
His club vice president, a 28-year-old man from Hammond Park, has been charged with grievous bodily harm and stealing.
A 32-year-old man from Secret Harbour, who is a member of the Rockingham chapter of the Rebels OMCG, has been charged with grievous bodily harm and stealing.
Investigations will continue into a number of items seized today, including pepper spray and what is believed to be human growth hormones.
The trio were refused bail and will appear in the Rockingham Magistrates Court on Friday.
