A new type of high-security apartment building has emerged in Australia’s inner city suburbs as residents are increasingly concerned about the safety of their balconies and other areas of their homes.

The controversial “vandalism protection” measures in Melbourne’s outer suburbs have been the focus of a number of high profile incidents.

Last week a man was killed and several people injured when a balcony in a home in the CBD was smashed by a hammer.

The same day a Melbourne man was fatally stabbed by a man wielding a machete in his own home.

In Sydney’s west, police said they were investigating a series of similar attacks on apartments and homes.

“We have been investigating these attacks on apartment buildings, particularly in inner suburbs, for quite some time,” Sydney police assistant commissioner Ian Stewart said.

“They are an emerging trend in the city, particularly around the inner suburbs and on the weekends.”

It’s something we are constantly working on and we are actively investigating.

“The use of balcony safety guards is not new in Australia, but the number of such incidents has increased in recent years.

The ABC has been tracking the rise in balcony incidents since it began to document them.

It has been the subject of an investigation by the ABC and several other news organisations since 2012.

The use is being increasingly popular among younger and poorer people, and often involves large groups of people, with one man being killed in a brawl at a Melbourne apartment in January.”

What it boils down to is people are using the balconies for more of a recreational purpose and a little bit of an excuse to be out there and be aggressive,” Mr Stewart said on Wednesday.”

You see them smashing things, they are swinging things, you see people breaking into houses and destroying things.

“In many cases, people are angry at the balconys and often resort to the use of “bait and switch” tactics.

The first victim of this type of attack was the man who was killed in Sydney in January, and police have described it as a “nightmare”.”

People who are involved in these incidents can be quite aggressive,” police Assistant Commissioner Stewart said, adding that the most common tactic was the use “bitch” tactics like hitting, kicking and throwing objects.”

Some people might think they can break through the security system and get through it and then they just throw stuff at the security guards,” he said.ABC/ReutersTopics:terrorism,law-crime-and-justice,federal-government,police,police-sieges,perth-6000,vic,melbourne-3000,sydney-2000First posted October 03, 2019 18:29:03Contact Victoria SmithMore stories from Victoria
