A man has been sentenced to a whole-life order, meaning he will spend the rest of his life in prison, for the murder of Sgt Matt Ratana, whom he shot with a gun he smuggled into a custody centre while handcuffed.
Last month, Louis De Zoysa, 26, was found guilty of killing Ratana, 54, by shooting him in the chest at point-blank range at a custody block in Croydon, south London, in September 2020.
