White supremacists are believed to have shot five protesters in Minneapolis who were demonstrating against the death of an unarmed black man who was gunned down by police on November 15.

The protest followed on from the death of Jamar Clark, 24, who was shot in the head by police while allegedly wearing handcuffs, according to witnesses.

The five people shot just before midnight on Monday all have non-threatening injuries, according to Minneapolis Police Department spokesman John Elder.

The shootings occurred near an alley about a block away from the 4th Precinct station, where protesters have been conducting a sit-in since Clark was shot.

Protesters who witnessed the violence claim the shooters were white supremacists.

Dana Jaehnert said one of the men had been wearing a mask and one was shouting 'the "n" word', she told The Star Tribune.

Black Lives Matter spokesperson Miski Noor said they opened fire on the group when a dozen protesters attempted to herd them away from the area.

Jaehnert said that's when she heard four gunshots. The attackers then fled.

A police source told KTSP that the suspects are believed to be white males wearing bulletproof vests.

Protesters have been at the 4th Precinct station in Minneapolis since Clark was fatally shot.

Mr Clark's brother Eddie Sutton said his family appreciates the protesters' efforts on behalf of their brother but believed that they should suspend their week-long demonstration.

He said they should go home 'out of imminent concern for the safety of the occupiers'.

Minneapolis police say five people had injuries that were not life-threatening after the shooting. No one was in custody, and police were asking anyone with information to come forward.

Black Lives Matter Minneapolis said in a statement earlier Monday that the group would announce the next steps it had planned at a news conference Tuesday.

Officers Mark Ringgenberg and Dustin Schwarze were suspended on full pay following the shooting.

The probe by the Minnesota Bureau of Criminal Apprehension is likely to last between two and four months.

The FBI is also conducting a parallel investigation into the shooting.

The officers were interviewed by investigators last night, said their union president Lt. Bob Kroll.

Kroll said the officers had told him they were certain Clark was not in handcuffs when he was fatally wounded.

But witnesses have told the official investigation team that he had been shackled when the shot was fired and still had one handcuff on his wrist when put into an ambulance.

A 10-year-old schoolboy gave a dramatic account of how he witnessed Clark being blasted in the head by a police officer after being handcuffed.

The boy, speaking to Daily Mail Online with his mother's permission, has been interviewed by police and given a full statement.

The key witness told how he observed the shooting from his front door, around 15 yards away, after hearing the commotion of Clark being arrested.

Clark's death has sparked a fresh wave of political protests and more than 50 people have been arrested.

The schoolboy,Ze'Morion Dillon-Hokins has told investigators from the Minnesota Bureau of Criminal Apprehension, that Jamar Clark was handcuffed when he died from a gunshot wound to the head.

The investigators have been brought in by Minneapolis police to help prepare an independent report on the incident that has led protesters onto the streets leading to the arrest of 51 demonstrators.

The child, accompanied by his mother, was taken to a special child friendly suite in South Minneapolis, where he gave a statement that contradicted initial official claims that the victim appeared not to have been in handcuffs.

Ze'Morion, told Daily Mail Online he had been playing video games on his PS4 when he heard shouting and then saw Clark trying to gain access to the ambulance where his girlfriend was being treated.

'They asked him to step back. He was saying 'f*** you' to them.'

He said Clark put his hands up when police officers approached him and he was handcuffed.

The 24-year-old was 'choke-slammed down' by the officers right outside his front door, he said.

'Then they took out a gun and 'popped' him in the face. He took two more breaths. I saw the smoke from the gun.'

He said Clark was face down when he was shot and the officers 'flipped him over' after the gun had been discharged.

Ze'Morion said before Clark was dragged to an ambulance, one handcuff was removed while the other remained on a wrist.

A wooden stick, placed by investigators, marked the spot on Plymouth Avenue North where the incident happened, directly in front where the boy lives with his family.

His mother Tequila Dillon, 31, who has four other children, said: 'He was in shock afterwards. He was at home playing on his PS4 when he heard something was going on and went outside to see what it was.

'He saw it all and it has upset him. He came in and fell right over and said: "They are killing us."'

'I hope what he has told the police and the Bureau will help everybody get to the truth.

'I ain't understanding why the police are saying he wasn't handcuffed, when he clearly was. There were about 30 people who witnessed it.'

Clark, who was unarmed, was shot in front of the Ecks of the World private club, which had a social evening ending as police arrived with revelers leaving at around 12:45am early Sunday.

Police are understood to have seized CCTV video which may have captured the scenes across the street.

Another witness Darrell Gross, 48, whose home also faces the spot where Clark was shot, said: 'He was shouting 'f*** you, f*** you' at the police. But that ain't no reason to get shot. One officer had his knee in his back after they had slammed him.

'When they got him up after shooting him, he had one handcuff on one hand and the other had been removed.

'People were shouting that they had killed an unarmed man and other police had their guns out pointing at people and telling them to back off. Luckily they did.'

Supt. Evans confirmed there were handcuffs at the scene and part of the investigation was to establish whether they had been applied to Clark or not.

But Daily Mail Online can reveal that there is no body cam footage or dash cam footage of the incidents available to investigators.

The club's video does capture, however, 'portions of the incident' and has been handed to investigators.

Clark's father James Hill refused to call for calm and instead issued a rallying call.

His home is close to the Fourth Precinct police station which has been besieged by demonstrators led by the pressure group Black Lives Matter.

He told Mail Online: 'I wish I could burn that police station down for what they have done to my son.

'It was a cold blooded execution of a man whose hands were tied. Where is the justice in that?

'I can't describe seeing your son laying there in hospital with his eye shot out and being that way. He was as good as dead the moment the police shot him.'

'They kept him alive to buy some time while they figured out what to do. This is a terrible situation, but I welcome people protesting. That is another black life gone. That is again one too many.'
