The alleged gunman who is accused of opening fire in Ferguson on the anniversary of Michael Brown's death posed holding guns on Facebook and bragged about being a gangster.

Tyrone Harris called himself 'Ty Glocks' after the gun maker and claimed he was part of a group called 'Pistol Gang'.

He posed in multiple photos on Facebook with pistols and rifles whilst his friends waved wads of cash in front of the camera.

Harris also bragged in one post that he would 'do da hit by myself' and made gang signs for the camera.

The 18-year-old is currently in a critical condition in a hospital in St Louis, Missouri.

He has been charged with with four counts of assault on law enforcement in the first degree.

He has also been charged with shooting a firearm at a motor vehicle and is being held on $250,000 cash bond.

St Louis County Police say that Harris opened fire with a stolen Sig Sauer 9mm handgun on Sunday night and that they shot him when he fired at them.

Court records show that that in November last year Harris was arrested for having a stolen 9mm pistol.

A probable cause statement showed officers pursued and arrested him after driving down a one way street in a stolen car.

St Louis County Police Department released a video on Tuesday which they said shows 18-year-old suspect Tyrone Harris grabbing a gun (circled in red above) from his waistband

The last post on his Facebook page was from Sunday at 4.51pm and reads: 'I f*** around go on West Florissant tonight', referring to the street where the protests were happening and where he was shot by cops.

Another recent post reads: 'Aint no gang like my gang #pistolgang'.

Today it also emerged that footage from German TV network Ruptly captured the moment that Harris allegedly pulled out his gun from back of his pants.

The clip shows him running across the street towards where multiple gunshots were coming from as everyone else dives onto the ground.

The next time Harris was seen he was lying face down with blood stains on his torso having been shot by four plainclothes police officers after allegedly firing at them.

The footage by Ruptly, which is based in Berlin and is owned by Russia's RT network, was shot from the other side of the street from where Harris was.

It shows a different angle from the surveillance footage released by the St Louis County Police Department.

Harris' family have insisted he is a good kid and that he did not open fire at police.

Surveillance video had already been released that police say shows Harris with a gun - minutes before he allegedly fired at plainclothes officers.

Harris, 18, is currently fighting for his life in hospital after being shot by police in Ferguson on Sunday night during protests to mark the one-year anniversary of Michael Brown's death.

Footage from the 13-second video, taken from a local insurance company in Ferguson, was released on Tuesday by the St. Louis County Police Department.

Police said it shows Harris grab a handgun out of his waistband once shots are fired on West Florissant Avenue during the protest.

At the start of the video, a crowd is seen standing in front of shops and in a parking lot before they frantically disperse, taking cover behind cars, as shots are fired.

Shortly after, Harris can be seen grabbing a gun from his waistband, police said.

'The St. Louis County Police Department is releasing surveillance video pertinent to the investigation of the officer involved shooting of Tyrone Harris that occurred on August 9, 2015,' police wrote in the video description.

'The surveillance video is from Solo Insurance Services, located at 9197 W. Florissant, St. Louis, MO 63136.

'Detectives from the Crimes Against Persons Unit have identified the person in the video as Tyrone Harris.

'The video shows Harris grab a handgun out of his waistband once shots are fired during the protest in the W. Florissant corridor.'

County Police Chief Jon Belmar said that plainclothes officers had been tracking the man, who they believed was armed, during the protests when he spotted them and opened fire.

The officers returned fire from inside the vehicle. They then pursued the man on foot. The chief said the man once again fired on the officers, with all four continuing to fire back.

In an exchange of gunfire the officers wounded the suspect, according to police.

Harris was in critical condition on Monday at a St. Louis hospital. County police and Barnes-Jewish Hospital were unable to provide updates on his condition Tuesday.

Prosecutors charged Harris with four counts of assault on law enforcement, five counts of armed criminal action, and one count of shooting a firearm at a vehicle. His bond was set at $250,000.

Harris's father said his son did not have a gun.

'He was running for his ... life because someone was shooting at him,' Tyrone Harris, Sr. said in a telephone interview from his St. Louis-area home before the video was released.

Harris Sr. declined to discuss his son's shooting on Tuesday.

Activist groups, meanwhile, had said the plainclothes officers who shot Harris should never have been deployed to the scene.
