Police say Monday’s shooting that rocked Perth’s CBD was between two members of outlaw motorcycle gangs – the Mongols and an associate.

A 60-year-old man was caught up in the dispute, held at gunpoint and forced to drive along the Graham Farmer freeway before the Tactical Response Group (TRG) rammed the vehicle.

Police say there was an exchange of gunfire before they arrested a 28-year-old Bedfordale man, Joshua Alban Gomez, who has now been charged with a string of offences.

State Crime Assistant Commissioner Brad Royce said the two men have not been cooperating.

“As in most case the two men don’t want to offer up much of an explanation,” he told Gareth Parker on 6PR Breakfast.

“So we don’t know how to it started, we have some ideas which we will probably keep to ourselves for now, but the issue for us quite simply is we don’t want any outlaw motorcycle members wandering around our streets with firearms.

The carjacking victim remains in hospital following the crash, as does the accused.

Two police officers were treated for minor injuries.

The 28-year-old man will face Perth Magistrate’s Court via a bedside hearing from Royal Perth Hospital on Tuesday morning.
