US police officers who shot and killed an unarmed black man will not face any criminal charges.
The police officers who shot 22-year-old Stephon Clark in March last year will not face criminal action, officials have said.
Mr Clark's death prompted mass protests across the US after he was killed following a chase ending his grandparents' garden in California.
The two officers who shot him, Terrance Mercadal and Jared Robinet, unleashed their weapons on Mr Clark as they thought he was holding a gun.
However it turned out Mr Clark, who was a vandalism suspect, was merely carrying his mobile phone when he was shot seven times.
Sacramento County District Attorney Anne Marie Schubert concluded the pair acted within the law stating the evidence supported their account Mr Clark was moving towards them when they opened fire.
She added evidence including their reactions captured on body cameras supported the officers' statements they thought Mr Clark was pointing a gun.
Ms Schubert said the decision "does not diminish in any way the tragedy" and added: "We cannot ignore that there is rage within our community."
Mr Clark's family and supporters, including members of the Black Lives Matter movement, have expressed disappointment at the decision.
His mother also lambasted revelations which were made about her son's personal life.
It was noted Mr Clark was facing possible jail time after a domestic violence complaint two days earlier from Salena Manni, the mother of his two children, and had researched suicide websites including those that suggested using a tranquiliser which was among several drugs found in his system after his death.
"Whatever his character is or his actions prior to those officers gunning him down, is no one's business," said SeQuette Clark, who had a brief meeting with Ms Schubert before the announcement. "It's not justification. That's not a permit to kill him."
Black Lives Matter leader Tanya Faison criticised the sharing of certain details and said: "Those officers didn't know any of that when they had him in the backyard and they killed him."
Ms Manni, who was also Mr Clark's fiancee, said the decision continued a "the shameful legacy of officers killing black men without consequences".
Black Lives Matter protestors gathered outside a Sacramento Police department following the decision.
The Sacramento Police Officers Association and the police department did not respond to requests for from the two officers.
Police union president Timothy Davis said in a statement that the case "illustrates how complicated and dynamic a request for police service can be."
Sacramento police had noted they have not yet decided if the officers broke any department policies.
