Sergeant John Sheahan has confirmed that a Black Range Rover sport and a Maserati had stopped at a red light on the Las Vegas strip when the Range Rover opened fire on the Maserati.
Both cars went through the intersection. The Maserati hit a taxi. The driver and passenger of the taxi were killed after the taxi caught fire.
The driver of the Maserati died from gunshot wounds and the passenger was wounded. The Range Rover then fled the scene. Three other vehicles were involved.
Sergeant John Sheahan at the Las Vegas Metropolitan Police Department has described the gun fight which lead up to a huge crash which killed three people on a busy junction.
He said a "rolling gun battle" preceded the crash.
At least a further three people were hospitalised, including a passenger from the Maserati.
A tourist who witnessed the aftermath of the crash told KLAS-TV that the burning taxi looked like a fireball.
More people may be hurt, Sergeant Sheahan said.
It is the latest in a series of violent actions on the tourist corridor since the beginning of the year. Two people were critically wounded in a shooting at a parking garage 6th February, and a tourist was stabbed in an elevator at The Hotel at Mandalay Bay ten days later.
Three people were killed and at least three injured in a gun battle between moving vehicles that ultimately crashed at a busy intersection on the Las Vegas Strip, police have said.
A total of five vehicles were involved in the crash, including a taxi that burst into flames and killed two people around 4.30 am local time, at Flamingo and Las Vegas boulevards, said Sergeant John Sheahan.
People in a Maserati and an SUV were exchanging gunfire before the Maserati hit the taxi, he said.
The Maserati driver, the taxi driver and a taxi passenger were killed.
