Matt Cane, General Secretary of the Metropolitan Police Federation, said: "The Metropolitan Police Federation notes and welcomes the decision of the jury in the case involving PC Liam Newman.
"Society expects our officers to protect them and keep people safe. When officers are involved in operational incidents as a result of that expectation then society must provide police officers the legal care and backing needed to continue doing our jobs without fear or favour.
"Police officers are incredibly accountable for their actions - as we have seen in this case. But this incident occurred almost four years ago which is a concerning amount of time for this to carry on.
"We would now look for any potential conduct proceedings hanging over PC Newman to be dealt with expediently following this correct not guilty verdict and for PC Newman to be allowed to fully resume his career."
