" - Albanian Mafia commits a murder in Australia, shoots it with fear and publishes it online.

Jack Cheung, 35, was shot dead outside his home in Charlesford, northwest of Sydney, on Wednesday morning.

He was found lifeless at the entrance of his home in North Rocks Road, about 05:30, while his body was discovered only 90 minutes later when the plumbers arrived to work at the apartment.

A few hours later, New Police Detectives South Wales (NSW) made a public call for images from security cameras (CCTV) and car cameras (lovem) to help the investigation.

But it was the killers themselves who responded to this call, publishing motion pictures of air footage, where the author was seen approaching Cheung and shooting him dead outside his home.

Challenging images were published overnight on a social networking platform, accompanied by a brief message.

Hello, this is the Albanian mafia; we have a view of Mr. Cheung's execution from the gangs today at Carlosford. ”

This is disturbing,” said Police Deputy Commissioner Scott Cook.

The “is a new era in organised crime. ”

Meanwhile, NSW Police chief Mal Lanyon said he has his concerns, as the Sydney crime world is already regularly publishing images of mafia executions on public platforms.

Their internet modification could spur other people to take such actions,” he said.

Lanyon also added that this trend could turn against criminal gangs themselves.

GPS device found in victim's car

The release of drone images comes shortly after it was discovered that a GPS tracking device had been found and installed in Cheung's car before he was ambushed and executed.

Cheung lived in that apartment with his mother, who was on Wednesday rushing back from a vacation in Thailand.

The images of the security cameras show that the author arrived with a SUV at 5:31 p.m. and remained in the area for only three minutes. However, homicide detectives are still investigating the exact moment when the 35-year-old was wounded to death.

Police continue their search for the author and vehicle used by him.

According to 7 NEWS, Cheung's brother is a member of Coconut Cartel's one of Sydney's most notorious criminal groups, who appeared powerful in the city's crime world earlier this year.

Detectives are investigating whether the murder is related to the wars between criminal gangs.

The “is not something we exclude, but we can't even confirm at this moment,” Deputy NSW Police Officer Michael Marinello told reporters Wednesday.

Police also confirmed Cheung was known for the authorities. Last month he was submitted to court after being captured in possession of a weapon without permission.

Cheung was known in the neighborhood for his love of cars, and he even participated in competitions in Eastern Creek. Hyundai was his life and has now become a key part of the investigation into his death.

We saw Jack all the time. He was very kind, he never behaved badly,” said neighbors Isabel and Jeanette.

All he did was get into his car. ”

Neighbors were shocked by the early morning attack.

We have no idea. We're all in shock. Perhaps he was associated with the wrong people,” said Isabel and Jeanette.

Neighbors heard gunshots before the body was found

Neighbors told him 7 NWS had heard a gun shot about two hours before the body's macabre discovery was made.

Marinello said the investigations thus far indicate that several bullets were fired.

The “seems to be a very bold attack,” said Marinello.

We don't believe this was a random attack. We believe it's an isolated incident, and that's why we can assure the public that there is no constant threat. ”

There were people in the house at the moment of the event and they are working on our investigation. ”

Police will question witnesses and gather images from security cameras (CCTV), while preliminary investigations continue.
