Police investigating the fatal shooting of a man at Ravenhall, in Melbourne’s west, in February have been unable to determine a motive for the shooting and suspect the victim was shot by mistake.

Father of five, Ikenasio Tuivasa, 33, known to his friends and family as ‘Sio’, was shot while standing outside a pool hall in Westwood Drive just before midnight on February 27.

It’s believed a passenger in a Toyota Hilux ute called out to members of Mr Tuivasa’s group to get their attention before firing several shots.

Mr Tuivasa was shot in the upper body and died later in hospital.

A 24-year-old man from Endeavour Hills who was standing nearby suffered a serious injury.

Police have previously said Mr Tuivasa had a limited criminal history and there was nothing he had been involved with that would have led to the shooting.

Investigators have released CCTV of the vehicle, which is believed to be a 2017 Toyota Hilux SR5 dual-cab ute with a chrome roll bar on the rear tray and stock wheels.

Both occupants were perceived to be Pacific Islander in appearance, and it’s believed the passenger spoke Tongan.

Possible link to outlaw motorcycle gangs

Detective Inspector Tim Day said the pool hall where Mr Tuivasa was shot was frequented by members of the Hells Angels and Comanchero outlaw motorcycle gangs (OMCG), and that some of those members were at the venue the night before the shooting.

“It is believed a separate altercation occurred outside the venue on that previous evening,” he said.

“Intelligence indicates that a firearm was produced during this incident. Investigators are trying to establish whether this incident is linked to the shooting in which Sio was killed.”

Detective Inspector Day said it was possible Mr Tuivasa was shot by mistake.

“As we know – the type of characters running around in OMCGs are generally not rocket scientists, and there are a number of examples over recent years of OMCG groups not doing their homework and killing an unintended innocent victim.”

No arrests have been made and police have asked anyone with information to call Crime Stoppers on 1800 333 000.
