Louis De Zoysa has been given a whole-life sentence for the murder of former Met Police Sergeant Matt Ratana - who he shot in a custody centre in September 2020.
The sentence means the 26-year-old will never be released from prison.
Jurors were shown distressing CCTV footage of the 26-year-old gun fanatic using the legally-bought gun to shoot Sgt Ratana. Report by Chahalb. Like us on Facebook at http://www.facebook.com/itn and follow us on Twitter at http://twitter.com/itn
