UPDATED: A 23-year-old Comanchero Motorcyle Club nominee allegedly punched a woman and broke her jaw in Northbridge overnight.
A police spokeswoman said it would be alleged that the 29-year-old woman was punched in the face by the Beechboro man just after midnight at Hit Studio Karaoke Box on Francis Street.
She said a scuffle broke out between several groups who were having functions in the bar’s private rooms.
One of the groups included members and associates of the Comanchero Motorcycle Club.
The spokeswoman said the force of the punch broke the woman’s jaw, dislodged several teeth and knocked her to the ground.
She was taken to Royal Perth Hospital, where she will have surgery today.
It is unclear if the 29-year-old has suffered any permanent injuries.
Detective Senior Sergeant Darren Hart from the Gang Crime Squad said police would not be intimidated by outlaw motorcycle gangs.
“OMCG members often use threats and intimidation to discourage the reporting of such crimes,” he said.
“Police take a strong stand to provide a consequence to these criminal groups for behaviour such as this.”
In a separate incident two hours later on nearby Lake Street, a 23-year-old man was knocked unconscious outside the Library Nightclub.
He was taken to Royal Perth Hospital with non-life threatening injuries.
Police arrested a 24-year-old man over the incident which happened between 1.45am and 2am. No charges have been laid and the incident is not related to the attack at the karaoke bar.
Anyone with information about either incident is asked to call Crime Stoppers on 1800 333 000.
