Bodycam footage has captured the moment a driver opened fire on two police officers before he was shot dead.

The footage, released on Friday, shows officer Richard Nelson, 33, and another unnamed officer having a tense conversation with Miguel Salas, 25, after they approached his car.

They argue with him about leaving his vehicle, but he resists, saying he's done nothing wrong - and then in a split second he opens fire on them.

Metro Police Sgt. Jeff Clark said in a press conference that police had been called out to a report of a suspicious vehicle linked to a stolen cellphone.

They had been told that the car occupied by Salas (pictured) was linked to a stolen cellphone. He argued until one of the officers called for backup

They approached Salas' car at 4.15pm after finding it parked in front of a business in the 4100 block of West Tompkins Avenue.

The video, filmed on Nelson's bodycam, begins with Salas protesting his innocence and refusing to get out of his vehicle.

After he reaches for something inside, Nelson restrains his left hand and the other cop joins them at the driver side window.

When Nelson calls in backup, Salas seems to sigh and pulls a handgun out with his right hand. Both cops back up suddenly in opposite directions as the shots ring out.

Salas initially fires towards the other officer but then turns and shoots at Nelson, who returns fire.

At that point he opened fire on both of them. Both cops were hit, but not seriously injured; Salas was shot in the head and died. The bodycam footage was released on Friday

'Shots fired! I've been hit! Shots fired, I've been hit!' he shouts into his radio as he reloads and waits for backup.

He's heard coughing badly as he waits for help. Finally, another LVMP cruiser arrives and picks him up as the video ends.

According to Clark, Nelson - a father of four - was wearing a bulletproof vest when he was hit, and was later discharged from hospital, Fox 5 Vegas reported.

The other officer was also hit, but his uniform saved him. His condition is unclear.

Selas died after being hit in the head. Police recovered two pistols they say belonged to Salas.

One was a fully loaded .25 caliber pistol, and a .40 caliber pistol that was used to fire on police

The .40 has a magazine capacity of 15 rounds; the one that was found had one round in the chamber and two in the magazine.

Nelson, who has been with the department since 2009, is on paid administrative leave while the case is reviewed.
