Tensions are running high among bikies in Western Australia after the home of a senior Hells Angels leader was targeted in a drive-by shooting.
Gang crime squad detectives are investigating after shots were fired at the home of Dayne Brajkovich in Ascot, in Perth's inner-east, on Tuesday night.
Police Commissioner Chris Dawson has confirmed five to six shots were fired but nobody was injured.
It comes amid ongoing tensions after senior Rebels bikie Nick Martin was shot dead by an apparent sniper while attending a drag racing event at Perth Motorplex in December with his wife and other associates.
A $1 million reward is being offered for information leading to the arrest and conviction of his killer.
Martin was bashed by Brajkovich, the Hells Angels sergeant-at-arms, at a Scarborough pub weeks before his death.
"There's a lot of tension out there at the moment," Mr Dawson told Perth radio 6PR on Wednesday.
"We're obviously not happy about this and the bikie gangs will know this because we have a very big operation, Operation Ravello, which is suppressing a lot of bikie activity."
Mr Dawson said people had been removed from the Ascot home and were being spoken to by police but indicated they were not cooperating.
More than 100 officers have been tasked to Operation Ravello, with the brazen public slaying at Perth Motorplex sparking fears of gang retributions.
The venue in Kwinana Beach has been returned to its owners after police scoured surrounding bush in a bid to determine where the shooter was located.
Martin's son-in-law Ricky Chapman, a former Bandidos member, was also wounded in the attack and a five-year-old boy was grazed by a bullet fragment.
Detectives have since launched multiple raids on properties associated with outlaw motorcycle gangs.
Martin had survived an attempt on his life in 2011 when he was shot by a Rock Machine bikie.
