More charges have been brought against a man accused of murdering a Metropolitan Police sergeant at a south London custody centre.
Louis De Zoysa, 24, allegedly shot Matt Ratana in the chest while handcuffed during a search at a police station in Croydon in the early hours of September 25, 2020.
He was charged with murder, possession of a prohibited revolver with intent to endanger life and having ammunition.
In a hearing at the Old Bailey on Monday, a 10-count indictment was brought against De Zoysa.
It includes charges of possessing a pipe gun, dummy launcher, shortened infantry rifle and gas/blank-firing revolver.
De Zoysa is accused of discharging four bullets in a holding cell at Croydon Custody Centre during the incident last year, in which he was also injured.
The first shot hit 54-year-old Sgt Ratana in the chest, causing a fatal wound, while he was also hit in the leg.
De Zoysa received a life-threatening bullet injury during the incident and is recovering in hospital under police guard.
The defendant, of no fixed address, was not present for the short hearing before Judge Mark Lucraft QC.
The judge set a further review hearing for February 25.
