A senior bikie has been callously dumped outside a hospital with gunshot wounds and burns after trying to leave an outlaw motorcycle gang, police say.
The 51-year-old man was a "patch member" of the Comanchero outlaw motorcycle gang, police said.
He was found collapsed outside Rockingham Hospital's emergency department in Perth's south about 10pm on Thursday with gunshot wounds in his upper body and leg.
He also suffered burns to his legs indicating someone had tried to remove tattoos relating to the Comanchero gang, Detective Senior Sergeant Anthony Thompson said.
"We believe he was dropped off and just left there, which is a rather callous way to deal with someone with life-threatening injuries," he told reporters on Friday.
"This person has now been left with life-changing injuries, solely because he was a member of an outlaw motorcycle gang."
The man was "very well known" to West Australian police.
"He was a patch member, and he was a senior member, and he held a position of authority within that club," Det Sen Sgt Thompson said.
"This is another timely reminder that the outlaw motorcycle gang community is dangerous and harmful.
"If you're thinking about joining an outlaw motorcycle gang, think again."
The man has been transferred to the Royal Perth Hospital where he is in a serious but stable condition.
Det Sen Sgt Thompson said WA police would be keeping an eye on motorcycle gangs but confirmed there was no ongoing risk to the public.
"We will be monitoring outlaw motorcycle gangs hard over the next few days to ensure that the community is safe," he said.
