Violence not random – police

On Thursday night, a man (31) allegedly killed an acquaintance (35) and seriously injured another (32) in an alleged knife attack at a Landsdale Road property in Landsdale.

On Friday morning, residents at a Darch home on Kingsway discovered a man (37), unknown to them, wounded on their driveway and seeking help.

Six days prior, a man was believed to have been stabbed and died after an attack at a Dericote Way residence in Greenwood.

Superintendent Allan Adams acknowledged the incidents were alarming, but reassured residents they were rare. He emphasised the violence was not against random victims, but people known to the alleged attackers.

"There have been some high-profile incidents of late, but I can assure the community that these (alleged) offenders targeted persons known to them " these weren't random events,� he said.

He said the North West Metropolitan district, which extends from Two Rocks across to Wanneroo and down to Cottesloe, had the lowest rate of what police statistics term as "offences against persons" in WA.

This includes assaults.

"We�ve had a 2 per cent decrease in non-domestic assaults in the last 12 months," he said.

"That's only 37 fewer offences, but that's 37 fewer people assaulted in our community."

Police charged Mirrabooka man Trung Trong Tang with murder and unlawful wounding over the Landsdale incident.

Mr Tang faced Joondalup Magistrates Court on Friday, was remanded in custody and is due to appear in Stirling Gardens Magistrates Court on August 26.

Landsdale Residents Association president Domenic Zappa said many residents were shocked and concerned about the two stabbings in the local area last week.

"It is quite sad to see this level of violence and crime in our community," he said.

He suggested worried residents attend the association’s next meeting at 7.30pm this Wednesday at Warradale Clubrooms, where a police officer would answer questions.

Police are still looking for suspects in the Greenwood and Darch matters.

The mother of Ryan Mathew Boudville, who was killed in the August 8 Greenwood incident, paid tribute to her son in a death notice on Friday.

"Tragically taken from us" you were constantly loved and will be forever remembered. Rest in peace our Chuchy. We will love you forever,� the notice said.
