Two Bicton residents have described the horrific scene after two cars collided in a fatal crash at an intersection near their home last night, sending one of the cars smashing into trees on their property.
Resident Stephen Pickford said the crash "sounded like an explosion" as the car slammed into the trees.
Police say the drivers of the two cars were allegedly involved in a robbery and assault earlier in the evening at Point Walter Reserve.
Three people were involved in that offence, police said. One left the scene in a Holden Astra and the other in a Commodore.
The driver of the Commodore had been involved in a short pursuit with police before the fatal crash.
Police say they aborted the pursuit. The Commodore was spotted again a short time later but before police could chase the car it collided with the Astra at the intersection of Pembroke and Harris streets, Bicton.
A 28-year-old man driving the Astra died at the scene.
A man, who was allegedly driving the Commodore involved in the crash, was taken to hospital.
Bradley Ross Taylor, 18, appeared in the Fremantle Magistrate's Court this afternoon on several charges including aggravated burglary, aggravated assault, driving to escape police, dangerous driving causing death and failing to stop.
His lawyer told the court he intended to apply for bail when he appears in court again on Friday.
Taylor was remanded in custody.
Mr Pickford said the Astra slammed into four trees on his property.
Mr Pickford said: "The car slammed into it sideways and the car disintegrated.
"It was the most horrific thing I have ever seen.
"We heard this explosion, I can't describe how loud it was, it was incredible.
"The car spun him around and slammed the Astra against these trees and the other car ended up about 100m down the street."
Mr Pickford's wife, Jill, saw the crash through the front window of their house.
"I saw all the debris and the dust flying across the garden and the picket fence flying around," she said.
"It was like a bomb going off.
Mr Pickford told ABC radio the police car had its lights and siren on but was not pursuing the Commodore at the time of the crash.
He said another resident, a retired ambulance officer, attempted to help the man in the Astra but it appeared that he had died.
Mr Pickford installed a camera to monitor the intersection after residents' concerns about safety.
The camera captured the moment of the crash as the Commodore travelled through the stop sign.
Police said this morning that they had responded to an earlier incident where a 50-year-old man was assaulted and had an electric scooter stolen.
A police spokesman said one of the offenders had left the area in a Holden Astra and the other in a Holden Commodore.
There was a short pursuit when police saw the Commodore travelling along Point Walter Road.
Pembroke Street residents said last night they saw one car travelling up the street with a police car in pursuit shortly before the crash.
"The car came up Pembroke with a police car chasing it," one neighbour said.
Another neighbour said he heard a loud bang before the crash occurred, before a shirtless man got out of one of the vehicles and attempted to run.
Police blocked off the intersection for several hours last night as officers from the Major Crash Squad investigated the incident.
