Perth man Paul Marsandi, 37, member of the notorious Mongols bikie club, was last week arrested and charged by police, just days after posing in photos with gang members.
The home of a Mongols bikie has been targeted in a drive-by shooting while a heavily-pregnant woman and her daughter were inside - as fears grow of an all-out turf war between rival gangs.
Neighbours in Port Kennedy in Perth s outer-south heard banging and shouting about 2.50am on Thursday, March 11 police said.
The property on Sirius Place is understood to belong to Mongols identity Jason Gastarov - who previously defected to the gang from the Rebels.
A pregnant woman and her five-year-old old daughter were believed to be sheltering inside the home at the time.
Thursday s shooting follows Rebels bikie kingpin Nick Martin, 51, being shot dead at the Perth Motorplex in Kwinana Beach on December 12.
