Phone video crucial help as police investigate violent gang attack in Sydney’s west

Police are confident video of a vicious gang attack on teenager Denzil Parker in a Sydney McDonald’s carpark will help them find the culprits.

Up to 50 young men armed with bats and golf clubs can be seen attacking the teen in the phone vision.

The victim was left unconscious and bloodied on the ground in Glenmore Park in Sydney’s west.

The group dispersed before police arrives but three 17-year-old males claimed they had been attacked.

One of the teens had a minor head injury but refused treatment.

All three of the teens have refused to cooperate with police.

Witness Hayden Green used his phone to capture pictures of the incident.

“He looked unconscious, there was a fair bit of blood coming from his face,” he said.

“I was going to McDonald’s to get a sundae and to see that right at the drive-thru, it’s quite intimidating.”

The scale of the attack will prove a challenge for investigators with officers looking for dozens of witnesses.
