Today, Tuesday May 20th, is phone in a bikie day.
Police ask the public to provide information about illegal gang activity.
Police say that some members of bikie gangs do more than just ride bikes and their illegal activities affect the entire community either directly or indirectly.
"The Western Australia Police ran a similar appeal in 2009 that led police to the prosecution of 69 gang members, over 189 charges and seized drugs worth almost $11 million on WA streets," a statement from the police said.
"By phoning in, the community can help police in this fight without being fear of identified."
The community can report any illegal activity associated with bikie gangs by calling Crime Stoppers on 1800 333 000.
