WA police have apprehended a 25-year-old man who they believe can assist with their investigation into the fatal shooting of Joe Versace in the northern Perth suburb of Gnangara last week.
Mr Versace was found dead by police at a workshop premises on Sydney Road last Thursday afternoon.
Detectives confirmed the victim had links to outlaw motorcycle gangs and said the attack was targeted.
Police were keen to know the whereabouts of Joshua Duperouzel, who they apprehended in Belmont on Monday.
No charges have been laid against Mr Duperouzel.

Police were also searching for a black BMW X5, registration 1FBE 666, which detectives believe may have been involved in the incident.
They are interested in its movements on Thursday September 29, between the early afternoon and late evening, prior to its recovery in Glen Forrest.
On Friday, Police Commissioner Col Blanch vowed to crack down on criminal gangs across the state.
"If you get out of line, you start doing things like this, then the gang crime squad will come for you," he said.
"If people think that they can, in cold blood, shoot people in Western Australia, then the police will be coming for them."
The gang crime squad and other specialist units raided properties in Scarborough and Greenfields over the weekend.
"The police are actively still searching houses, still speaking to people that we should be speaking to, we haven't stopped, nor do we intend to," Detective Inspector Quentin Flatman said.
