article: These are the horrific final moments of a 44-year-old suspect who was apparently accidentally shot dead by a 73-year-old reserve deputy last week after he fired his handgun instead of his Taser. In the footage, released by police, deputies are filmed chasing after Eric Harris, first by car then on foot, in Tulsa, Oklahoma, on April 2 after he fled during a sting operation in a nearby parking lot. Once they catch up to Harris, they tackle him to the ground and order him to lie on his stomach. Robert Bates then yells, 'Taser! Taser!' - but takes out his service weapon and pulls the trigger. After firing one round into Harris, the former full-time officer drops his gun from the recoil and says in shock: 'Oh, I shot him! I'm sorry.' Harris then starts yelping on the ground, while pleading for help. WARNING: GRAPHIC VIDEO . Chase: This newly-released video of Eric Harris's fatal shooting shows deputies chasing after Harris, first by car then on foot, in Tulsa, Oklahoma, on April 2 after he fled during a sting operation in a nearby parking lot . Fleeing: The deputies run after Harris, who was allegedly caught trying to buy drugs and a gun from cops . View from the ground: Once they catch up to Harris, they tackle him to the ground and order him to lie on his stomach. Robert Bates then yells, 'Taser! Taser!' (pictured) - but takes out his handgun and pulls the trigger . The fatally-wounded man, who is being held down by his neck by the deputies, exclaims: 'Oh my god, he shot me! He shot me! He shot me, man.' He then adds: 'Oh, my god. I'm losing my breath.' Shockingly, one of the deputies replies: 'F*** your breath.' Another calls Harris, who is black and dressed in shorts and a T-shirt, a 'motherf***er' and tells him: 'You shouldn't have f***ing ran.' Following the incident, during which the deputies do not appear to realize Harris has been fatally injured and even tell him to 'shut the f*** up', the suspect was hospitalized. He died an hour later. The footage, obtained by NewsOn6, comes as a number of US shootings  involving police officers and  black suspects have hit the headlines. Many of the suspects were unarmed at the time. In the April 2 incident, Bates accidentally fired his gun thinking that he had pulled out his Taser - as proved by the fact he did not expect the weapon to recoil, the Tulsa County Sheriff's Office said. Bates, who had been monitoring the situation from afar, ran up to Harris in a bid 'to get the situation under control', before mistakenly firing his gun instead of his Taser, according to on-site deputies. Apology: After firing one round into Harris, the former full-time officer drops his gun from the recoil and says in shock: 'Oh, I shot him! I'm sorry' (pictured) Harris then starts yelping on the ground, while shouting, 'Help!' Shooting: This photo shows a deputy bending down to pick up Bates's dropped gun following the 'accidental' shooting in Tulsa earlier this month. Harris is being held down on the ground, out of shot, by other deputies . Terrified: The fatally-wounded man, who is being held by his neck and back by the deputies (pictured), says: 'Oh my god, he shot me! He shot me! He shot me, man.' He then adds: 'Oh, my god. I'm losing my breath' Suspect: Shockingly, one of the deputies replies: 'F*** your breath.' Another calls Harris (pictured in a police mug shot released d by officials on April 4) a 'motherf***er' and tells him: 'You shouldn't have f***ing ran' Harris, who was being restrained at the time, had  allegedly fled after he was caught trying to buy drugs and a gun from deputies posing as dealers in the parking lot of a nearby dollar store. Major Shannon Clark told CNN: 'They were struggling trying to get him into custody, he ran up trying to use a less lethal device, trying to get the situation under control. 'Inadvertently he discharged a round from his service weapon.' He added: 'Did an accident happen? Sure. But is it accredited to his age? Or was it accredited to the rapidly evolving situation? I guess that will be determined in the investigation.' Bates, who has been a reserve since 2008, is the chief executive of Robert C Bates LLC, a Tulsa-based insurance company, who worked as an officer assigned to the Violent Crimes Task Force. Fatal: Following the incident, during which the deputies told Harris to 'shut the f*** up', the suspect was hospitalized. He died an hour later. Above, blood appears to be running down Harris's arm at the scene . Scene: In this photo, which has been partially blanked out by the Sheriff's Office, deputies are pictured at the scene of the incident. The deputy in the foreground of the frame is holding down Harris following the shooting . He has also spent time with the Tulsa Police Auxiliary. Speaking to local site News OK, Bates said: 'It was me. My attorney has advised me not to comment. As much as I would like to, I can’t.' According to Tulsa Police, Harris had met an undercover officer to sell him a 9 mm semi-automatic pistol and 300 rounds ammunition. He fled the scene when deputies tried to arrest him, it is alleged. The suspect then fought with another deputy when he was shot, police said. He was gunned down accidentally by Bates after officers 'observed him reaching for his waistband area ... causing concern for the deputies' safety,' authorities told CNN. Officers had been monitoring Harris as part of an investigation into the trade of methamphetamine. As he met with undercover deputies to allegedly hand over the drugs, he is accused of offering to throw in a sawed-off gun. Confusion: Bates, 73, accidentally grabbed his pistol and shot Harris (right, in a previous mug shot) dead, according to Tulsa police. Bates is classified as an advanced deputy. The incident is now under investigation . His convictions include escaping prison in 1990, robbery with a dangerous weapon in 1999, and making threatening phone calls. According to Tulsa Police, Harris' killer, Bates, is classified as an advanced deputy. Reserves are 'basic', 'intermediate', or 'advanced'. The qualify for 'advanced', officers are required to have a minimum of 320 hours of training and 25 hours of training a year. During the annual field training program, they are tested on how to use and identify lethal and non-lethal weapons. With the same power as paid deputies, reserves can conduct their own investigations, make arrests and work on task forces. The cause of Harris's death is under investigation.
