A MOTHER has called for action after her disabled son was allegedly bashed for the third time in less than 12 months outside a western Sydney shopping centre.

Smartphone video of the latest alleged incident shows the 15-year-old waiting for a bus and texting on his phone outside Westpoint Blacktown cinema before he is punched by another teenager.

Seconds pass before another charges and lunges at him, before he falls back and cracks his head on a bench.

The boy spent two days in hospital following the attack on August 10.

Blacktown police charged a 16-year-old boy with assault occasioning actual bodily harm.

In another incident on September 28 last year, the disabled youth was attacked and repeatedly kicked before being pushed onto a road.

The youths who attacked him received a youth caution.

On November 19, at the Blacktown bus interchange, bullies allegedly attempted to rob him of his scooter, attacking him and rubbing chewing gum in his hair.

Two teens were charged over the alleged incident, one of whom has pleaded not guilty, and the matter is still before Parramatta Children’s Court.

Another pleaded guilty and was given a 12 month good behaviour bond.

The boy’s mother said there needed to be consequences for the daylight attacks.

“It is time a torch is shone on what is happening in Blacktown because the violence is getting worse,” she said.

Her son has autism and she said he had difficulty making friends but he wanted to fit in.

“All a mother ever really wants to do is protect her kids and see them happy. I know he struggles every day and he is vulnerable and a lot of people don’t ‘get’ him,” she said.

“When I first saw the video, I was in despair, for him to be so oblivious to what was going on, and to be targeted. I felt so helpless. I still get choked up about it now.”

But she it was difficult for him to relive the traumatic incidents in a court.

“He had to go through the traumatic experience of being a witness and all they got was a slap on the wrist.”

The teen spent two days in hospital following the August 10 attack, and was later readmitted after suffering seizures and fainting.

The brave victim said he thought the bullies picked on him because he was an easy target.

“Maybe because I am the weakest one, I am the smallest, they know that I don’t know how to fight,” he said.

Now he can’t leave the house by himself for fear of being attacked.

“Going out to Blacktown by myself, going to the library, looking in shops … I can’t really do that any more,” he said.

“It is the fear of being on the floor and not (being able) to get up.”

Numerous shopkeepers The Daily Telegraph spoke to at Westpoint said violence in the area was out of control, with fights between the same school-aged youths occurring every day.

They spoke on the condition of anonymity, saying speaking out would put a target on their heads.

“(Security guards) are scared of these people because they get into fights literally for a living because they have nothing else to do,” one said.

“They technically would be school-aged kids but they don’t go to school.

“Normally we have a group of people smoking and spitting as people walk past, just being gross.”

Another shopkeeper said the youths often threatened her, and at one stage were throwing large marbles from a third storey balcony onto shoppers below.

A worker at another store said most of the youths carried knives, showing The Daily Telegraph an image from a fight last week in which a man was said to have drawn a 30cm knife.

Westpoint centre manager Agata Rynkiewicz said the safety of customers, retailers and employees was taken very seriously by the shopping centre.

“Westpoint Shopping Centre is monitored by a large security team who patrol the centre 24 hours a day, seven days a week, coupled with an extensive CCTV network.”

She said the centre worked closely with local police and provided support community youth programs in the area.

“Westpoint is an important community gathering place for people of all ages and we continue to be committed to providing them with a safe and secure environment,” Ms Rynkiewicz said.
