White cop who killed George Floyd's by kneeling on his neck is know for violence against back suspects.

Two of the cops fired over the arrest of black man George Floyd have already been investigated for their roles in previous use-of-force incidents, it has been revealed.

Derek Chauvin, 44, the officer filmed kneeling on Floyd's neck during his arrest, is a 19-year veteran of the force who was investigated over a fatal police shooting in 2006.

Floyd died Monday in police custody, hours after footage showed Minneapolis cop Chauvin knelt on him for eight minutes during the arrest for forgery.

Now it's been revealed Chauvin was investigated for his role in the 2008 shooting of Ira Latrell Toles during a domestic assault call. Toles was wounded after police said he went for an officer’s gun and Chauvin shot him.

Two years earlier Wayne Reyes, 42 was killed by officers after allegedly pulling a shotgun on the six cops, which included Chauvin,

A second officer involved in Monday's arrest, Tou Thao, was part of a $25,000 out of court settlement after being sued for using excessive force in 2017.

In a lawsuit obtained by the DailyMail.com shows Thao was sued for using excessive force in arrest where he was accused of punching and kicking a handcuffed suspect 'until his teeth broke'.

The second officer, Thao, was sued in 2017 by Lamar Ferguson who said the cop had used excessive force during his arrest.

A lawsuit obtained by DailMail.com states 'Defendant Thunder and Defendant Thao’s use of unreasonable force on Plaintiff, in the form of punches, kicks, and knees to the face and body while Plaintiff was defenseless and handcuffed, was so extreme that it caused Plaintiff to suffer broken teeth as well as other bruising and trauma.'

The case was settled out of court for $25,000 after Thao said he had punched Ferguson after he 'actively resisted arrest'.

He wrote: 'After — at this point he’s actively resisting arrest. He — so I had no choice but to punch him. I punched him in the face.'

All four officers were fired Tuesday. DailyMail.com has contacted Minneapolis police for comment and for the officers' full records with the department.

Chauvin is said to be represented by lawyer Tom Kelly. He was Jeronimo Yavez' attorney after the Minnesota police officer fatally shot Philando Castile during a traffic stop in 2016.

Yavez was found not guilty on all three charges by a jury in 2017.

The remaining two officers have been identified by the city as Thomas Laneand J Alexander Kueng.

Both were reportedly rookie cops who were still in their probationary periods, according to the StarTribune.

The FBI and state law enforcement authorities have launched an investigation into the man's death.

Minneapolis cops in riot gear last night fired rubber bullets and tear gas at thousands of defiant protesters who took to the streets to demand justice for Floyd and protesters began to gather Tuesday for a second day of demonstrations.

The victim's heartbroken family have called for the cops to be charged with murder.

Minneapolis Police Chief Medaria Arradondo announced Tuesday that four officers are now 'former employees' of the force.

'We know there are inherent dangers in the profession of policing but the vast majority of the work we do never require the use of force,' Arradondo said.

Floyd's death has caused outrage across America with political figures and celebrities including Cardi B, P Diddy and Demi Lovato voicing their anger.

Floyd worked as a security guard at Conga Latin Bistro, a local bistro in Minneapolis. The bar's owners have described him as a 'very calm, nice guy' who was not the type to be 'aggressive' or 'disrespectful'.

Ben Crump, the attorney for the victim's family has demanded officers face murder charges over the killing and said this is 'worse than Eric Garner' because the officers held Floyd down by the neck for eight minutes.

Crump pointed to the similarities in the case with the death of unarmed black man Garner who died in 2014 after he was placed in a chokehold by New York City police and pleaded for his life, saying he could not breathe.

Parallels have already been drawn between the two cases but Crump described Floyd's death as even 'worse'.

'I mean it was eight minutes. It is in many ways worse than Eric Garner as they have his knees on his neck and he is begging, pleading for not one minute, not two minutes, not three minutes but eight minutes – begging them to let him breathe so we have 'we can't breathe' again in 2020,' he said.

'I think the officer should be charged with murder,' Crump told 

TMX.news 

, about Chauvin.

'It was clear that he was begged by public bystanders to take his knee off George's neck.'

A

 report 

released Wednesday detailed how medics worked on a 'unresponsive, pulseless’ Floyd, who was pronounced dead at hospital.

The report states: 'Medics performed pulse checks several times, finding none, and delivered one shock by their monitor. [Floyd’s] condition did not change.'

Crump also called for the other officers involved to be charged as accomplices to murder.

'They were supposed to protect and serve citizens like George. We in black America, we are done dying at the hands of the people that are supposed to protect and serve us,' he said.

'Please, please, please, I can't breathe. Please, man,' Floyd, who is shirtless, begs the cop.

The officer repeatedly tells him 'Well get up and get in the car then,' while he continues to pin Floyd to the ground.

Floyd responds 'I will' but the cop continues to hold him to the ground by his neck.

'My stomach hurts, my neck hurts, everything hurts,' Floyd is heard gasping at one point, before saying he needs water.

After several minutes, one of the officers tells him to 'relax.'

'Man, I can't breathe,' Floyd responds, before eventually passing out.

An ambulance then arrives and police officers move the man's limp body onto a stretcher.

In the footage, shared by onlooker Darnella Frazier, multiple witnesses were also heard arguing with the two cops over their excessive use of force.

New video footage also shows the moment Floyd was pulled from his car by police.

Cops were reported to have located Floyd, who was suspected of forgery, in his car around 8pm before ordering him to exit the vehicle, according to a police statement. A spokesman alleged Floyd got out of the car before 'physically resisting officers'.

However, new video footage, obtained by

 FOX 9 

, has shed light on the moments leading up to Floyd's arrest, showing two officers manhandling and forcibly removing him from his car as he is placed in handcuffs outside the Cup Foods grocery store on 38th and Chicago Ave in south Minneapolis.

Floyd appears to be complying with officers and not resisting arrest before an altercation ensues.

Additional CCTV footage obtained by CBS News has also emerged from a nearby restaurant showing parts of the altercation between Floyd and officers on the sidewalk.

The new videos have shed light on the events leading up to Floyd's death. In the CCTV footage from a restaurant, a handcuffed Floyd is seen sitting on the ground as a police officer, who was not seen in the original viral video, speaks to him before picking him up and holding him against the wall.

Another police officer then comes over and helps escort Floyd to a nearby squad car before the clip ends.

The events to follow were then captured in a separate video widely shared on Tuesday, which showed Floyd pleading with the cop to stop, saying 'please, please, I can't breathe' and 'My stomach hurts. My neck hurts. Everything hurts', as he is pinned to the ground.

George Floyd was not only a rapper who recorded music with the late influential hip hop artist DJ Screw and a star football player for his Texas high school team, but a father of two young girls, including a six-year-old, who he now leaves behind.

The 46-year-old leaves behind two daughters, including six-year-old Gianna Floyd who lives with her mother Roxie Washington in Floyd's former hometown of Houston.

Washington told the Houston Chronicle her ex was a 'gentle giant'.

'People mistake him because he was so big that they thought he was always a fighting person but he was a loving person,' she said. 'And he loved his daughter.'

George Floyd (pictured in the 1990s, in jersey 88) was not only a rapper who recorded music with the late influential hip hop artist DJ Screw and a star football player for his Texas high school team, but a father of two young girls, who he now leaves behind. Floyd was loved by many on the football team at Jack Yates High School in Houston where he played wide receiver. A fellow teammate tweeted his sadness and anger when he learned of Floyd's death

'I don’t even have words for it,' Washington, 38, told the paper. 'It’s cruel. They took him away from my daughter. She’ll never see her father again.'

In an interview with CBS This Morning, Floyd's cousin said his daughter is ‘not doing well’ after learning of her father's untimely death.

Washington, who attended a 100-strong protest in Houston after Floyd's death, said he was born in North Carolina and moved to the city's third ward as a baby.

Floyd was loved by many on the football team at Jack Yates High School in Houston where he played wide receiver in the 1990s.

A fellow teammate tweeted his sadness and anger when he learned of Floyd's death.

He wrote: 'We played together on the same summer league team (after our freshman year) in the BCI league.

'Floyd was a cool dude. Hate to hear that he passed. Now I’m just realizing that Floyd is the guy killed by police. I hope the officer who did this meets the same fate. That would be justice.'

Archive footage from 1992 shows Floyd scoring a dramatic touchdown at one of the Yates games.

The school's coach, M.J. Hickey Jr, posted a photo on Twitter of the late player with his team and the caption '#88 #RIPGeorgeFloyd'.

'I don’t even have words for it,' Washington (left with Floyd center), 38, told the paper. 'It’s cruel. They took him away from my daughter. She’ll never see her father again.'
