A brawl in Perth that left a teenage boy dead and five in hospital reportedly started out as an organised fight between two rival groups of teenagers.
Police said the brawl started in a park in Canning Vale about 3:00pm on Thursday, before spreading to a nearby liquor store and a fast food outlet on Ranford Road.
Two youths were stabbed during the fight, but neither received fatal injuries.
A short time later a car ploughed into a group of four teenage boys aged between 16 and 17, who were waiting at a bus stop on Eucalyptus Boulevard.
One of the boys, aged 17, was thrown through the windscreen of the car and was taken to hospital, where he later died.
Three of the injured have been taken to Royal Perth Hospital in a serious but stable condition, and two others are being treated in Fiona Stanley Hospital.
Inspector Tony Hill said the driver and passenger of the vehicle involved in the crash, understood to be a man and a woman, were arrested.
"We now have two people in custody at Armadale police station who are assisting us with our enquiries," he said.
The Education Department has confirmed that students from Canning Vale College were involved in the melee or witnessed the fighting.
A spokeswoman said support including counselling services will be offered to students.
'They were covered in blood'
Witness Cecilia, who did not want her surname published, helped the some of the people hurt by the car while her son called emergency services.
"First of all we heard a big bang and me and my husband were sitting in front of the TV, there was [a] casualty next to the car — they were covered by blood," she said.
"I was so panicked I just went back inside my house to get towels and bed sheets to help.
"My youngest son stayed with one of the casualties lying on the ground and gave him reassurance and he was the one who called the emergency services.
"It's just a bit of a shock."
Cecilia said she spoke briefly to a woman who got out of the car.
"She kept saying 'I was the driver, I was the driver,'" she said.
Tensions between groups of teens sparked brawl
Despite early reports of tensions between ethnic groups in the area, Detective Sergeant Matt Lewis told ABC Radio Perth police did not believe the brawl was gang related.
"This was unrelated young people that have ended up having a disagreement and it's just ended up spilling out and becoming bigger than it really needed to be," he said.
"No gangs were involved with this at all."
Yesterday, police cordoned off three separate crime scenes — one at the fast food store, one on the bus stop at Eucalyptus Boulevard and another at the liquor store.
A red sports-style car was seen at the Eucalyptus Boulevard scene with its windscreen shattered. Shoes were also seen strewn by the side of the road.
Police from the homicide and major crash are investigating.
A 'quiet' neighbourhood
Local resident Lloyd Rego, who has lived in the area for four years, said the neighbourhood was generally quiet.
"It's definitely been a quiet area and a good area to live, so I'm really surprised and shocked at what's happened here," he said.
However, he said he had heard reports of young people getting into trouble.
"At times at night this place could get a little dodgy with youngsters."
