A man has been charged over an alleged street race that killed two students, and critically injured a third on a suburban street in Sydney's west on Wednesday.
The three Bangladeshi students were travelling along Canterbury Road in Belmore at roughly 3.40am when their Toyota Aurion crashed into a power pole and "disintegrated", police said.
The horrific crash killed the driver Fahim Rahman Aunik, 22, and his passenger Saqlaen Utsha.
Another passenger, Rifaat Mustafa, is in a critical condition at St George Hospital.
Police are investigating if the three men were involved in a street race, saying speed was definitely a factor in the crash.
"We've examined a number of other vehicles from that scene and we're not ruling out a street-racing event," Superintendent Stuart Smith told reporters.
Officers spoke to the occupants of a white Nissan Skyline that was at the scene.
On Thursday afternoon, officers from the Metropolitan Crash Investigation Unit arrested a 27-year-old man after he attended Campsie Police Station.
Police will allege the man was driving the Nissan Skyline that was involved in a street race with the Toyota Aurion in the moments before it crashed.
He was charged with driving in a dangerous manner, organising, promoting or taking part in a street race, and exceeding the speed limit by more than 45km/h.
The 27-year-old was conditionally bailed and is due to appear in Burwood Local Court on March 22.
He told media after the crash: "I was driving around 60, 70[km/h]. I don't know how fast he was going, but I think he had some problems with his car [the Toyota Aurion]."
"And I just pushed my brake and I seen [sic] he was just sliding into the third lane and suddenly he's gone behind me," he said.
Earlier on the same night, two people were injured when their car crashed into a power pole in a separate crash in Cabramatta.
Police said the Toyota Camry involved in that crash was travelling north on Gladstone Street when it left the road and hit the power pole, snapping it in half.
Police said the male driver, 28, and his female passenger, 32, were not believed to have been wearing seatbelts.
Paramedics took both patients to Liverpool Hospital with head injuries.They are both understood to be in stable conditions.
On Saturday, three Sudanese women were killed when the car they were riding in hit a power pole during a police pursuit in western Sydney on Saturday.
