A new dash cam video has been released as evidence unravels surrounding the shooting of unarmed father-of-four Walter Scott in South Carolina.

The latest footage shows there was a man in the car with Scott when the pair got pulled over in a parking lot as part of a routine traffic stop on Saturday morning.

After failing to produce insurance papers, Scott fled the car and ran into the park where he would be shot dead by Officer Michael Slager.

In the moments after Scott and Slager ran from the parking lot, the passenger can be seen standing against the car being searched by another officer - as they both stare towards the scene of Scott's death.

SCROLL DOWN FOR VIDEO

Questioned: New video shows Walter Scott's passenger being questioned as Scott and Slager fled into a park

He was then taken to another patrol car and questioned, while officers rushed to the scene of Scott's death

It is not known what time the footage was taken, and whether Scott had been shot by this point.

The footage starts with Scott's passenger walking around the car, putting his phone on the trunk and his hands in the air.

The officer pats him down and checks inside his pockets.

Then the pair look over towards the park and exchange words, which cannot be heard over the music in the patrol car.

They then walk off, apparently towards another patrol car.

Authorities said he was questioned further before being released.

On Thursday, the first part of the dashcam video was released showing the moment Walter Scott and his passenger were pulled over.

Scott and Officer Michael Slager can be seen engaging in a civil discussion.

The camera on Slager's patrol car captures him telling Scott his third brake light is broken, before asking him to produce insurance papers.

Scott, who appears to be accompanied by a person in the passenger seat, explains he does not have any documents as he has yet to officially buy the car.

'I haven't bought it yet, I'm about to do that Monday.... My car is down,' he says.

The officer appears calm, checks his licence, then tells him: 'I'll be right back with you.'

When Slager returns to his vehicle, Scott flees, running towards the park where he would die moments later.

Off camera, a scuffle can be heard, with shouts of 'Taser, Taser, Taser!' and 'Get on the ground!'

The sounds on the recording, released by the South Carolina Law Enforcement Division, are the only record of the apparent altercation, which Slager claims prompted him to shoot Scott dead.

The South Carolina cop insists he tried to sedate Scott, but the father-of-four grabbed the Taser and fled.

Slager's account has been called into question after a shocking video taken by a witness shows the officer shooting Scott in the back.

It is claimed Scott ran because he feared being arrested for failing to pay a child support.

In the dash cam footage, captured from Slager's patrol car, the officer explains, 'The reason I've pulled you over is because your third brakelight is out.'

The conversation is muffled, with music playing in Slager's car obscuring the sound.

He can be heard asking Scott for his licence, registration and insurance card.

Scott responds that he doesn't have papers as he has not yet to bought the car.

'Alright let me see your licence,' Slager replies. 'So you don't have any papers in the glove pocket?'

Scott repeats that he does not and he is paying for the car on Monday.

Slager returns to his car.

A minute later, Scott opens the door, and gestures to Slager, who shouts, 'you've got to stay in the car!'

Scott then sits back inside the car - and moments later flees.

The only other footage of the incident shows the moment Scott was shot. Released earlier this week, it begins in the vacant lot apparently moments after Slager fires his Taser.

Wires which administer the electrical current appear to be extending from Scott's body.

As Scott turns to run, Slager draws his pistol and, only when he is 15 to 20 feet away, starts to fire the first of the eight shots at his back.

The video shows Slager handcuffing Scott's lifeless body.

Footage then appears to show Slager jogging back to the point where the Taser fell to the ground, bringing it over to Scott's body around 30 feet away and dropping it next to him.

It is only after two-and-a-half minutes that Slager is seen placing his hand on Scott's neck in an apparent attempt to check his pulse.

A black colleague then arrives and puts on blue medical gloves before handling the body, but is not seen performing first aid.

They are joined by a third officer, who also does not appear to tend to the victim.

Questions over the conduct of the North Charleston police department were growing on Thursday, and in particular how Officer Slager was able to escape scrutiny from his colleagues after he fatally shot Scott in the back.

On Wednesday local authorities refused to say whether other police officers will be charged over the shooting of Scott. Seven other officers were at the scene immediately after the shooting.

Reacting to the video, Scott's brother Rodney said it looked as if the officer 'was using my brother for target practice.'

'We were shocked, definitely shocked,' Rodney Scott told the New York Daily News.

'I'm angry, but he's going to have to give an account for what he did, that was just a horrible thing that he did.'

In an interview with Good Morning America earlier in the day, Mrs Scott said: 'When I looked at that tape, it was the most horrible thing I've ever seen, I am very very upset concerning it it. I almost couldn't look at it.

'To see my son running defensively and being shot – it just tore my heart to pieces. I pray that this never happens to another person – this has to got to stop.'

Sat between her other son, Anthony Scott and the family's lawyer, Mrs Scott was visibly distressed as she added: 'From a child he has been raised in the church.

'From day one he sang in the choir, he played the drums he would call his mom every single day.

'They never got in trouble they had a beautiful childhood and I had no problem.'

Another of Walter Scott's brothers, Anthony, said when he arrived at the scene where his brother died he instantly felt something was not right instantly.

'The police told me he had died. That is all they gave me.

'I already knew he had been Tasered – I thought that's what had actually happened. He had gotten Tasered to death.

'But then my nephew told me how he had died.'

'I thought that my brother was gunned down like an animal,' he told CBS.

'It was just unbelievable to me to see that.'

The parents of Walter Scott told the Today show on Wednesday that they wanted justice for their son.

'It would have never come to light. They would have swept it under the rug, like they did with so many others,' Walter Scott Sr said.

Mr Scott Sr added: 'The way he [Slager] was shooting that gun, it looked like he was trying to kill a deer... I don't know whether it was racial, or it was something wrong with his head.'

The family's lawyer Chris Stewart said they will be 'seeking recovery to the full extent of the law.'

'We can see how disgraceful the incident this is. His civil rights were directly violated and we're going to be filing a major civil lawsuit against all the responsible parties from this tragedy.'

Slager was charged with murder on Tuesday and could face the death penalty after the incendiary footage emerged.

The officer had previously defended his actions, saying he feared for his life after Scott wrestled his Taser from him during a scuffle.
