A ballistics expert has demonstrated to a jury how an antique revolver alleged to have been used to kill a Met police custody sergeant worked as the second day of a murder trial got under way.
Members of the jury in the trial of Louis De Zoysa, 25, who is accused of murdering Sergeant Matt Ratana, 54, at a custody block in Croydon, south London, on September 25 2020 while he was handcuffed, were allowed to hold the gun and fire it at Northampton Crown Court on Thursday.
