Dayne Brajkovich — one of WA’s most notorious gang figures — has been attacked with a knife after violence erupted between bikies at a concert at Kings Park. The heavily tattooed former Hells Angels sergeant-at-arms was “targeted” outside the Ministry of Sound concert on Friday night about 9.50pm, during an altercation with a group of outlaw motorcycle gang members. Witnesses who were leaving the music event described seeing at least six people involved in a brawl before people rushed to a bloodied Brajkovich, 44, who had a “serious” laceration to the left side of his neck. “There’s been an altercation, what appears to be, a person was subject to an attack with a knife,” a police spokesperson confirmed soon after. A St John WA spokesperson said one person was rushed to Royal Perth Hospital from the scene on Lovekin Drive with serious injuries. Detectives — including those from the gang crime squad — remained at the scene late into Friday night. A police helicopter was circling above Kings Park in the wake of the incident. Gang crime detectives are now investigating whether the surprise slashing was an act of retribution by his former Hells Angels bikie club, as police revealed ongoing concerns for the 44-year-old’s safety on Saturday. WA police officer in charge of gang crime detectives Anthony Thompson renewed calls for witnesses to the bloody brawl. “This was a targeted attack, and the general public has no cause for concern,” Det. Sen. Sgt Thompson said. “At this stage, we believe the incident is a result of an in-house gang-related issue between the Hells Angels and a former member. “The parties involved are known to each other and the possibility this incident is the result of a retribution issue is certainly an avenue we are investigating.” Police did not confirm if the attack was an assassination attempt and did not comment on the specifics of the weapon used besides it being a “small” “edged weapon”. No arrests have been made as police continue their inquiries into the incident after men — who did not attend the concert — fled the scene on motorbikes. Police also confirmed they have conducted inquiries with Brajkovich following the incident. It comes as The West revealed the former bikie walked himself out of Royal Perth Hospital before he was tailed by a police convoy. Brajkovich rose to infamy several years ago after he brutally bashed late Rebels boss Nick Martin in Scarborough just weeks before his assassination at Perth Motorplex in 2020. He was famously kicked out of the Hells Angels last year, claiming he and the president at the time did not see “eye to eye”. “Me and the Perth president of the Hells Angels didn’t see eye to eye on something and I couldn’t get my head around it,” he told The West Australian earlier this year. “One Friday night I went to the clubhouse early because I knew he’d be there. I didn’t have anyone else, so I brought Jacinta. She would follow me anywhere. “I brought my favourite homemade steel knuckledusters to see if they still worked. “To be honest, he (the gang president) had a broken leg and was on crutches, but he was always boasting about being ex-military and ex-SAS. “I had him screaming for his life with my two fists and with two members on my back. “I threw a stool on his sore leg just to top it off and we both walked out of there.” Brajkovich made headlines again when the Perth Mint’s lax financial controls came under the spotlight in March, after he used a debit card to buy $27,000 worth of gold in June 2022. His lawyer claimed the transaction only required his client to produce a driver’s licence, despite the Mint being required to perform rigorous background checks on any customer deemed “high-risk”. In 2021 the ex-bikie survived a drive-by shooting at his Ascot home and has since pointed the finger at rival Comanchero bikie Jason Kemp as being the triggerman. Kemp was found dead in the private pool of his luxury Broome villa in February this year. His death was not suspicious. Last month Brajkovich raised eyebrows when he listed his old bikie gang merchandise on Gumtree. The collection included a double-bladed axe that was given to the feared outlaw on the one-year anniversary of his being made the Hells Angels’ sergeant-at-arms.
